Person-colour synesthesia

This type of synesthesia consists of the involuntary association of one or more colours to known persons (friends, family, etc.). The perception may be simply a colour with no other properties, or the colours might have texture, shape, a three-dimensional presence, a spatial location and even rhythm or movement, and occasionally images. The associated photism normally appears after getting to know the person, i.e. some hours, days or weeks after the initial contact or after several encounters with the person, sufficient to form a good idea of who they are, what they are like as a person and what the synesthete’s relationship with them is, and once the colour has been triggered it remains constant and only changes in exceptional cases, which are explained below.

(There is another type of synesthesia where colours are associated with people, but in this case it refers to strangers rather than people the synesthete already has a relationship with: the photisms are perceived on the first sighting of the person in question and they correspond to the synesthete’s intuition of what kind of personality they have. To find out more on this type, go to the page on personality-colour synesthesia.)

What aspects determine the colour perceived?

In person-colour synesthesia, the aspects that determine the associated photisms are usually one or more of the following: personality; character; the relationship with the person; their physical appearance; their voice; the colour of their hair and eyes; the clothes they usually wear; their skills and abilities; and also some intuitive aspects such as feeling that they are hiding their true personality, for example. Basically, the colour corresponds to the general impression the person puts across after getting to know them sufficiently. For some synesthetes, the aspect of the person that creates the strongest impression determines the colour, while for others several of these aspects combine in a pattern or mix of different colours.

Few colours or many

For some person-colour synesthetes, each individual person they know has a different colour or shade/mix/pattern of colours and the repertoire is therefore practically infinite, while others only have a limited number of concurrent colours. Although it is more common for a wide range of different colours to be perceived, I am aware of one synesthete who only has two: all the people she knows are either blue or yellow (here). 

Additional perceptions

Sometimes the synesthetes' perceptions are much more than just chromatic, and it is possible for a person-colour synesthete to have very complex concurrents involving not only colour (together with texture, shape, depth, spatial location, rhythm, movement…) but also, in some cases although it is more uncommon, a pictorial image. 

Here is an example of a synesthete who perceives shapes and textured colour combinations for the people they know:

"Many people have their own abstract portrait in my head. My one friend is a black picture with glass texture in the middle that curves around... and there are 4 white rectangles at the bottom left. Another friend is a pale green sort of smudgyness, and blue with the same sort of smudginess at the bottom. My childhood babysitter was all rectangles most white and black and a few grey.”

This evocative description is by a person who perceives atmospheres combined with objects:

“My favourite professor is electric sugar and feels windy, if that makes sense, like fresh air everywhere.
My neighbours are rubber pots and pans.
My best friend is a dark blue cement candle in the dark kind of person but has a pink bubblegum name.”

There is another example of images being perceived for people here, on the page on "Figurative images as a synesthetic concurrent".

What might the different colours mean?

The meaning of each colour is different for each synesthete. As the colours are not consciously assigned or chosen but simply “appear” involuntarily, the synesthete is not aware of what each colour means unless they actually think about it and work out the code of correspondences. So for example, for one specific synesthete a “purple person” could be someone with depressive tendencies, while for others their purpleness could correspond to any other trait: intellectual, shy, bad-tempered, happy-go-lucky, straight-haired, spiritually inclined… Sometimes the same colour can have more than one meaning, so two people you know could be perceived as being the same colour, but for different reasons. The textures, exact hues, shape, spatial location and movement also have different meanings for each synesthete. Sometimes it is impossible to know or put into words the exact meaning of all these elements: it is just something very intuitive.

Here are a couple of examples. This synesthete has colours for personality:

"I have absolutely picked common threads with the common colors. For instances, I am a blue. We tend to be introverts, philosophers, scholars, etc and prone to moodiness. I am intimidated by most reds and in general, I don't like them. They tend to be aggressive, loud, argumentative, etc although not all bad, they are also very charismatic, attractive usually, witty, and ambitious.”

Conversely, for the person in this next example, the colours can represent what they perceive to be their relationship - or possible future relationship - with the person in question:

“The most dominant colours I feel for people are green/yellow and purple.

Green/yellow is for people who are just not the same as me, when I was younger it was a colour that I could best describe not the same is a similar feeling to someone being in your year at school but in the other class.

Purple is for “my people”, I don’t know how but it’s for people I just know are the same and I could be friends with.”

Prevalence of this type of synesthesia

Person-colour is a relatively common type of synesthesia, and although as far I am aware no studies on its prevalence have ever been carried out, my personal impression (received from observing the relative amount of contributions in online discussions about this type and from listening to synesthetes’ descriptions of the types they have in real life) is that around 10% of the synesthete population could have it, at the very least, and probably more. It could perhaps be considered one of the coloured sequence synesthesias, although it has some characteristics that make it particularly interesting.

Stability and consistency

As I’ve already mentioned, the colours evoked by this type of synesthesia are stable: once perceived it is rare for them to change and they are normally associated with the person in question for the rest of their lives. Very gradual shifts are occasionally mentioned - I have read an account by one person-colour synesthete who says that people's colours tend to start off being lighter and then become bolder and brighter the longer the relationship has lasted, for example, and it is also known for a person's colour or colours to "fade" if the synesthete has not seen them for a long time. But a sudden dramatic colour change seems only to occur in two cases: 1) if for any reason a significant change is perceived in the person’s character or personality, or 2) if there is a major change, especially a sudden one, in the type of relationship the synesthete has with them. Here is an example:

"Rarely do they change and so far, in both of those instances, I feel it coincided with drastic personality changes from mental disorder, or perhaps my own shift in understanding of them."

Is it beneficial for anything?

An interesting aspect of person-colour synesthesia is that it can actually be useful in day-to-day life. People’s colours represent what the synesthete has intuitively recognised about the person observed over time, and they are often a more accurate perception than those we distinguish on a conscious level or can put into words. Speaking from personal experience, I tend to trust my synesthetic colours more than my conscious opinions, which can be more influenced by external or conventional factors and even by the opinions of others, simply because I know from experience that they are more likely to be right. I see this as a better level of intuition. This is my own personal experience and may of course not be the same for other synesthetes, but the close relationship existing between intuition and person-colour synesthesia is uncontestable. Here’s another description by someone who has noticed something similar about his own case:

“The colors seem to know people better than I do a lot of the time. For instance, I know three people with white. A few weeks after meeting the third, I realized that they were all distant to me, in that something made me feel like I couldn’t approach them or get to know them.”

(Source: Dogstomp, in his daily autobiography comic. 2017.)

Another instance of how person-colour synesthesia can be useful is for categorisation: as an involuntary aid to memory. (It’s interesting to note that this is also clearly the case for some other types such as grapheme-colour or spatial sequences of time units or other concepts).

“To me everyone has color, sometimes shape and sometimes texture or depth. It helps me remember people.”

Associators, projectors and auras

Like other varieties of visual synesthesia, this type has associative and projective versions: many person-colour synesthetes are "associators" and perceive their photisms in the mind’s eye or merely as a strong impression, while others (the "projectors") actually see them physically. In this latter case they see the colours around, beside, in front of or above the person observed. This can be called “aura synesthesia”. Go to the page on aura synesthesia

Video and TV

Person-colour synesthesia mainly occurs with people known in real life, although some synesthetes also have colour concurrents for people familiar to them through other channels: if they often chat to them over the internet, for example, or see them frequently on TV. Politicians and other public figures are a good instance of this, and colours for youtubers have also been reported).

Influences from other types of synesthesia

Person-colour synesthesia should not be confused with the type where people have one or more colours evoked by the letters making up their names (grapheme-colour). In this case the colour has nothing to do with the personality or any other impression the person puts across, and people with the same name would always have the same colour (all Edwards would be green, for example). When both types of synesthesia, person-colour and grapheme-colour, coexist in the same synesthete things can start to get interesting, as they receive two colour impressions at the same time. The stronger of the two associations might win, one colour might influence the other and create a mix or pattern, or the colour of their name might be just one of many colour concurrents experienced for that specific person, all perceived at the same time. Grapheme-colour synesthetes tend to perceive the colours of their letters as being pleasing or "right", and this account by a synesthete with both grapheme-colour and person-colour synesthesia shows the effect that occurs when the colours of the person and the letters in their name coincide:

“Names have colors to me, but they usually don't match that person’s color. And when they happen to by coincidence ohhhh boy is it amazing.”

(Source: This comment on Reddit/Synesthesia. 2018.)

Another type of synesthesia that can determine or contribute to a person’s colours is voice-colour synesthesia: the person can take on the colour of their voice, or it might form part of their palette if they have several at once.

Did you know...?

Many person-colour synesthetes are incapable of seeing their own colour. This is probably due to the fact that we do not perceive ourselves in the same way as we do other people.
