Autism and Colour: Do Autistic People See the World Differently?

Have you ever wondered whether the red you see is the same red someone else sees? We might agree that something is red, but does that mean we experience the colour in the same way?

For some autistic people, colours can be a source of great joy. Bright colours may be beautiful, exciting, or fascinating. For others, those same colours can feel overwhelming or even uncomfortable. And some of us experience both, depending on the colour, the lighting, or how we are feeling that day.

But do autistic people actually see colours differently, or do we respond to them differently?

Research suggests that autistic people can differ in their colour preferences and sensory responses. For example, one study found that autistic boys were more likely to prefer green and brown, and less likely to prefer yellow, than non-autistic boys. ^[1]Atypical Color Preference in Children with Autism Spectrum Disorder (Grandgeorge & Masataka, 2016)

More recent research has begun exploring how sensory sensitivity may influence the colours autistic people enjoy and how preferred colours might support visual attention.

So, what does the research actually tell us about autism and colour?

How do we see colour?

To understand why people might experience colours differently, it helps to know how colour vision works.

At the back of our eyes is a thin layer of tissue called the retina. It contains two main types of light-sensitive cells:

• Rods help us see in dim lighting, but they do not allow us to distinguish colours.
• Cones allow us to see colours and fine details, especially in brighter lighting.

Most people have three types of cones, each responding to a different, overlapping range of wavelengths of light.

When light enters our eyes, these cones respond and send signals through our visual system. Our brains compare these signals, allowing us to distinguish red, green, blue, and the many colours in between. ^[2]How the Eyes Work (National Eye Institute)

But identifying a colour is only one part of how we experience it.

Think about a bright yellow wall. Two people might agree that it is yellow, yet have very different reactions. One might find it cheerful and energizing, while the other finds it uncomfortable.

There are several parts to our experience of colour:

• Colour detection: Our ability to distinguish one colour from another.
• Perceived intensity: How bright or vivid a colour appears.
• Sensory response: Whether a colour feels comfortable, distracting, or overwhelming.
• Emotional response: Whether we associate a colour with happiness, calmness, excitement, or dislike.

These experiences are connected, but they are not the same. You can identify a colour perfectly well and still find it unpleasant to look at.

What does this mean for autistic people?

Research suggests that autistic people may process certain types of visual information differently. Some studies have found strengths in noticing fine visual details and processing specific features of what we see. ^[3]Enhanced Perceptual Functioning in the Development of Autism (Mottron et al., 2006)

However, these differences do not necessarily mean that autistic people have different rods or cones, or that we detect colours more accurately.

Our brains play an important role in how we interpret and respond to visual information. This brings us to an interesting question: when an autistic person describes a colour as unusually intense, what are they actually experiencing?

Do autistic people experience colours more intensely?

Some autistic people describe colours as unusually bright, vivid, or overwhelming. A red sign might feel difficult to look at, or a brightly decorated room might become exhausting after a while.

But does that mean the colours themselves appear more intense?

Research has found that autistic people are more likely to experience differences in sensory responsiveness, including heightened sensitivity to visual stimulation. However, being more sensitive to something does not necessarily mean perceiving it more intensely. ^[4]A Meta-Analysis of Sensory Modulation Symptoms in Individuals with Autism Spectrum Disorders (Ben-Sasson et al., 2009)

Is it the colour or the brightness?

Imagine walking into a room with yellow walls, colourful furniture, and bright overhead lighting.

You might love the colours but find the lighting unbearable. Or perhaps the lighting is fine, but the combination of colours makes it difficult to concentrate.

Several things could contribute to these experiences:

• Saturation: Highly saturated colours, such as vivid red or green, can appear particularly striking.
• Brightness: Strong lighting and glare can cause discomfort, even when the colours themselves are enjoyable.
• Contrast: Sharp differences between colours or between light and dark areas can make a space visually demanding.
• Sensory processing: How our brains respond to visual information may influence whether an environment feels comfortable or overwhelming.

For example, you might love yellow but dislike a brightly lit yellow room. Change the lighting, and the same colour may become much more enjoyable.

What does the research tell us?

A review of sensory research found that autistic people can experience both heightened and reduced responses to sensory information. Some may be particularly sensitive to certain sensations, while others respond less strongly or actively seek out sensory experiences. ^[5]Sensory Perception in Autism (Robertson & Baron-Cohen, 2017)

This helps explain why sensory experiences can differ so much, even among autistic people.

However, research on sensory sensitivity does not necessarily tell us whether autistic people see colours as more vivid. To establish that, researchers would need to measure colour perception directly rather than relying only on reports of discomfort or sensory sensitivity.

We cannot conclude that autistic people generally see colours more intensely than non-autistic people.

What we do know is that visual experiences can affect our comfort, attention, and enjoyment of our surroundings.

And this raises another question. If colours can affect us in different ways, do autistic people also have different preferences for particular colours?

Do autistic people prefer different colours?

Do you have a favourite colour? Perhaps there is a particular shade you love so much that you find yourself choosing it for your clothes, your home, or the things you collect.

Researchers have been exploring whether autistic people prefer different colours from non-autistic people. And some of their findings might surprise you.

Which colours do autistic children prefer?

In a 2016 study, researchers showed six colours to 29 autistic boys and 38 non-autistic boys, aged 4–17, and asked them to choose their favourites.

The autistic boys were more likely to prefer green and brown and less likely to prefer yellow than the non-autistic boys. However, there were no statistically significant differences in preferences for red, blue, or pink. ^[6]Atypical Color Preference in Children with Autism Spectrum Disorder (Grandgeorge & Masataka, 2016)

Why might yellow be less appealing?

The researchers suggested that sensory sensitivity could play a role. Yellow can appear particularly bright, and they wondered whether this might make it less comfortable for some autistic children.

Do sensory sensitivities influence our favourite colours?

More recent research has explored whether autistic people’s sensory experiences influence the colours they enjoy.

In a 2025 study involving 46 autistic participants, researchers examined colour and texture preferences alongside sensory processing differences.

Participants with greater sensory sensitivity tended to prefer softer colours, while those with lower sensitivity showed a wider range of preferences, including bolder colours. ^[7]Analysing the Impact of Sensory Processing Differences on Color and Texture Preferences in Individuals with Autism Spectrum Disorder (Liu, 2025)

Our colour preferences may be connected to how we experience sensory information.

Of course, colour preferences are also personal. Our experiences, memories, interests, and cultural backgrounds can all influence which colours we enjoy.

Why can some colours feel overwhelming?

Have you ever enjoyed looking at something colourful, only to find that after a while it becomes too much?

Perhaps you love colourful shops but find yourself feeling exhausted after spending time in one. Or maybe you enjoy bright artwork at home but struggle with the lighting and displays in a supermarket.

Sometimes the problem isn’t the colours themselves. It is everything happening around them.

Colour, brightness, and contrast

A colour can look very different depending on how it is presented.

For example, imagine your favourite shade of blue. Now picture that same blue on a brightly lit screen, surrounded by flashing advertisements and sharply contrasting colours.

You might enjoy the first experience but find the second uncomfortable.

Several features can influence how visually demanding something feels:

• Hue: The colour itself, such as red, blue, or green.
• Saturation: How vivid or muted a colour appears. A highly saturated blue looks more vivid than a soft, greyish blue.
• Brightness: How light or dark something appears. Strong illumination can also increase glare and discomfort.
• Contrast: The difference between colours or between light and dark areas. Strong contrasts can make certain visual features stand out.
• Visual complexity: The amount of information competing for our attention, such as patterns, signs, decorations, and moving displays.

A highly saturated colour is not necessarily brighter than a muted one. And a brightly lit room is not necessarily colourful.

These distinctions help explain why changing the lighting or reducing visual clutter may make an environment more comfortable without removing the colours we enjoy.

When the environment becomes too much

Think about a supermarket. There may be brightly coloured packaging, overhead lighting, reflective floors, signs, and displays competing for your attention.

For someone who is sensitive to visual stimulation, processing all that information can be tiring. It may become difficult to concentrate, find what they need, or remain comfortable in the space.

Research has found that autistic people experience a wide range of sensory differences, including heightened responses to visual information. These differences can influence how comfortable or overwhelming an environment feels. ^[8]Sensory Perception in Autism (Robertson & Baron-Cohen, 2017)

Fluorescent lighting can also contribute to discomfort. Some people are sensitive to glare or flicker from certain lights, even when the flicker is not obvious. Reflections from windows, screens, or shiny surfaces can add to the visual demands of a space.

Can visual overload affect how we feel?

When visual stimulation becomes difficult to tolerate, some autistic people may experience:

• Difficulty concentrating or finding what they are looking for.
• Eye discomfort, headaches, or visual fatigue.
• Irritability, stress, or a growing need to leave the environment.
• Sensory overload, particularly when visual demands combine with noise, movement, or other sensory experiences.

What about autistic people who love bright colours?

This is an important part of the conversation.

Some autistic people actively seek colourful experiences. They may love vivid artwork, brightly coloured clothing, decorative lighting, or collections filled with colour.

For these individuals, colour may be enjoyable, stimulating, or comforting rather than overwhelming.

And someone can enjoy bright colours while still being sensitive to particular lighting conditions or visually busy spaces.

Enjoying colour and experiencing visual sensitivity are not opposites. Both can be part of the same person’s sensory experiences.

Rather than assuming that autistic people need muted colours or plain environments, it may be more helpful to ask what each autistic person enjoys and what makes them comfortable.

Can colour be an autistic strength?

We’ve explored how colours can sometimes be uncomfortable, but what about the ways our visual experiences can be strengths?

Some autistic people are particularly good at noticing small visual differences, spotting patterns, or finding details that others miss. Researchers have been studying these abilities for years, and the findings are fascinating.

Seeing details others might miss

In a 2009 study, researchers found that autistic children performed better than non-autistic children on certain visual-search tasks. They were particularly good at finding a target hidden among other visual information. ^[9]Why Is Visual Search Superior in Autism Spectrum Disorder? (Joseph et al., 2009)

Other research has suggested that some autistic people show strengths in processing fine visual details. Rather than always seeing the overall picture first, they may be especially attentive to individual features. ^[10]Enhanced Perceptual Functioning in the Development of Autism (Mottron et al., 2006)

However, these studies did not establish that autistic people see colours more accurately. Being good at finding visual details is not the same as having superior colour vision.

Can our favourite colours help us pay attention?

A 2025 study explored an interesting possibility: could using an autistic child’s preferred colours help support their visual attention?

Researchers compared 23 autistic children with 28 non-autistic children, using eye-tracking technology to examine how they followed visual targets.

When autistic children were shown visual cues in their preferred colours, their visual tracking accuracy and attention improved. The researchers did not observe the same significant improvements in the non-autistic comparison group. ^[11]Effects of Color Preference on Visual Smoothness and Attention in Children with Autism Spectrum Disorder (Park et al., 2025)

When colour becomes a passion

For some of us, colour is much more than something we see. It can be part of what makes an interest so enjoyable.

Think about someone who loves arranging objects by colour, creating artwork, collecting colourful miniatures, or experimenting with different shades and patterns.

These activities may offer opportunities for creativity, careful observation, and personal expression.

Sometimes, the things that capture our attention can also become sources of enjoyment and opportunities to develop our skills.

Colour, emotions, and sensory regulation

Do certain colours make you feel happy or relaxed? Perhaps you have a favourite colour that you find yourself choosing again and again.

Our responses to colour are not just about what we see. They can also involve our emotions, memories, and sensory preferences.

Can colours affect how we feel?

Research involving the general population has found associations between colours and emotions. For example, people may associate some colours with calmness, excitement, happiness, or sadness. However, these associations vary across individuals and cultures. ^[12]Universal Patterns in Color-Emotion Associations Are Further Shaped by Linguistic and Geographic Proximity (Jonauskaite et al., 2020)

This does not mean that blue will make everyone feel calm or that yellow will make everyone happy.

Our personal experiences matter, too. A colour might remind us of a favourite place, a person we love, or something that brings us joy.

Can favourite colours help with sensory regulation?

Sensory regulation involves finding ways to manage sensory experiences so that we feel more comfortable and able to do what we need or want to do.

For someone who finds bright visual stimulation tiring, softer colours might make a room feel more comfortable. Another person might enjoy surrounding themselves with vivid colours because they find them stimulating or pleasurable.

The 2025 study by Liu and colleagues found that autistic participants with greater sensory sensitivity tended to prefer softer colours. Those with lower sensitivity showed a wider range of preferences, including bolder colours. ^[13]Analysing the Impact of Sensory Processing Differences on Color and Texture Preferences in Individuals with Autism Spectrum Disorder (Liu, 2025)

These findings suggest that sensory preferences may be relevant when choosing colours for our surroundings.

Colour and synesthesia in autism

Imagine hearing a piece of music and experiencing colours along with the sounds. Or looking at the letter A and knowing that, for you, it is always red.

For some people, these experiences are part of something called synesthesia.

Synesthesia occurs when one type of experience consistently brings about another, such as seeing colours associated with letters, numbers, sounds, or words.

What does synesthesia feel like?

Synesthesia can take several forms.

• Grapheme-colour synesthesia: Letters or numbers have particular colour associations. For example, someone might experience the number 5 as green.
• Sound-colour synesthesia: Sounds or music bring about experiences of colour.
• Sequence-colour synesthesia: Days of the week, months, or other sequences are associated with particular colours.

These associations are often consistent over time. A person who experiences the letter A as red may continue to experience it that way for years.

Not everyone with synesthesia literally sees colours appearing in front of them. For some, the colours are experienced internally or as strong, automatic associations.

Is synesthesia more common in autistic people?

Research suggests that synesthesia may be more common among autistic people than among non-autistic people.

In a 2013 study, researchers examined synesthesia in autistic and non-autistic adults. They found that 18.9% of autistic participants reported synesthesia, compared with 7.2% of non-autistic participants. ^[14]Is Synesthesia More Common in Autism? (Baron-Cohen et al., 2013)

Is synesthesia a strength or a challenge?

For some people, synesthesia is enjoyable. Colour associations may make music, words, or numbers feel richer and more interesting.

Others may find certain experiences distracting or occasionally overwhelming, particularly when several sensory experiences occur together.

Synesthesia itself is not an autistic strength or challenge.

Creating colour-friendly environments

Now that we’ve explored how colour can influence comfort, attention, and enjoyment, what does this mean for the spaces we live and work in?

You may have come across recommendations for autism-friendly colours. Often, these suggest using muted blues, greens, or neutral shades while avoiding bright colours.

But is there really one colour scheme that works for autistic people?

What does the research suggest?

Research into colour preferences and sensory processing suggests that softer colours may be more comfortable for some autistic people, particularly those with greater sensory sensitivity. ^[15]Analysing the Impact of Sensory Processing Differences on Color and Texture Preferences in Individuals with Autism Spectrum Disorder (Liu, 2025)

At the same time, an autistic person who loves vivid purple might feel happier surrounded by it than by beige walls. Someone else might find that same purple uncomfortable.

What can make an environment more comfortable?

Rather than following a fixed autism-friendly colour palette, it may help to consider a few practical changes:

• Adjust the lighting. Use dimmable lights, lamps, or natural light where possible, depending on individual preferences.
• Reduce glare. Consider reflections from screens, windows, and shiny surfaces.
• Make screens more comfortable. Adjust brightness, contrast, colour themes, or accessibility settings.
• Consider visual clutter. If a space feels overwhelming, reducing competing patterns and decorations may help.
• Choose colours you enjoy. Favourite colours can be incorporated through clothing, artwork, furniture, or personal objects.
• Allow flexibility. A colour scheme that works well for one person may be uncomfortable for another.

These are options to explore, rather than rules that every autistic person should follow.

What about schools and workplaces?

Colour choices can become more complicated in shared environments.

A classroom with colourful displays may be engaging for some students but distracting for others. An office with bright lighting and strongly contrasting patterns might be comfortable for one employee and exhausting for another.

Where possible, providing choices may be more useful than trying to create one environment that suits everyone.

That could mean offering adjustable lighting, quieter visual spaces, different screen settings, or opportunities to personalize a workspace.

Where are the gaps in research?

Several limitations are worth keeping in mind:

• Small samples: Many colour-preference studies involve relatively few participants, making it difficult to know how widely the findings apply.
• Limited research involving adults: Much of the research focuses on autistic children, and we know less about how colour experiences may differ across adulthood.
• Different sensory profiles: Researchers need to examine how colour experiences vary among autistic people who are sensory-sensitive, sensory-seeking, or both.
• Colour perception versus preference: Enjoying a particular colour does not tell us whether someone perceives that colour differently.
• Real-world experiences: Laboratory studies may not capture what it feels like to spend time in a colourful supermarket, classroom, or workplace.

We need to see more research that asks autistic people directly about their experiences.

What colours do we love? Which ones do we avoid? Do our preferences change depending on lighting, stress, fatigue, or the environment?

And are there ways our experiences of colour help us with attention, creativity, or enjoyment?

These questions could help researchers better understand both our sensory challenges and our strengths.

A colourful spectrum of experiences

So, do autistic people see the world differently?

When it comes to colour, we still don’t have a complete answer.

Research suggests that autistic people may differ in their colour preferences, sensory responses, and certain aspects of visual processing. But these findings do not mean that all autistic people see colours more intensely or prefer the same shades.

For some of us, colour can be overwhelming. For others, it can be a source of comfort, fascination, creativity, and joy. And sometimes, it can be all of these things.

Two people can look at the same colour, agree on what it is, and still have very different experiences of it.
