Grapheme-shape/texture/colour/image synesthesia

In grapheme-colour synesthesia, letters and/or numbers each have their own colours. However, some synesthetes perceive not only colour for these elements but also qualities such as weight, size, consistency or texture, or even a complete image (which is not common but definitely exists). The perceptions for each letter or number are consistent and tend not to vary throughout the synesthete’s whole lifetime, typically dating back to early childhood. If the perceptions are visual, projector synesthetes see them physically in space while associator synesthetes see them in the mind’s eye.

This type of synesthesia applies to letters or numbers, but in the case of letters it sometimes occurs that the concurrents are not perceived for each separate letter but only on seeing, hearing or thinking about whole words. For some people they are actually perceived in response to separate syllables, so for example a three-syllable word might have three different textures.


Here are some descriptions written by people with this type of synesthesia:


Texture:

“Well some of the letters that have describable textures are J and G which are kind of sticky and have a muddy consistency, S and C are crisp and smooth, and P is kind of powdery. And you’re right, now that I think about it numbers don’t have texture, its only letters because of the sounds they make.”

Colour/texture:

This is part of the alphabet of a synesthete for whom all the letters have colour and texture:

“l- tan, creamy peanut butter texture
m- pinky red, seems watered down
n- red, like an apple left in the store too long. Glossy but losing a bit of the gloss
o- sheen. Smooth like running your fingers along the top of water”

Shape/texture/image:

The writer Vladimir Nabokov was a synesthete, as were his mother, his wife and his son. He described his grapheme-colour synesthesia in his autobiography Speak, Memory. This is part of his interesting description:

The long a of the English alphabet (and it is this alphabet I have in mind farther on unless otherwise stated) has for me the tint of weathered wood, but the French a evokes polished ebony. This black group also includes hard (vulcanized rubber) and (a sooty rag being ripped). Oatmeal n, noodle-limp l, and the ivory-backed hand mirror of take care of the whites. I am puzzled by my French on which I see as the brimming tension-surface of alcohol in a small glass.”

Image:

The following person associates letters, numbers, personalities and colours with a precise, detailed image which appears to them automatically and consistently. Here is an example of some of their numbers and letters. It is interesting to note that upper case and lower case letters produce totally different images.

"1: a shallow, murmuring brook in the middle of the woods in a summer morning.
2: a tall, wooden ladder propped up against the wall of a Mediterranean-style house.
3: crisp fallen leaves scattered in the backyard of a suburban house
4: the stilts of a carnival clown whom you just noticed was walking right behind you.
5: an assortment of flowers haphazardly strewn in a woven reed basket.
A/a: the noon sun streaming through the trees of an orange orchard/text written in gold in a huge medieval tome.
B/b: a brick wall in the middle of a city as seen at 3pm/fluffy pillows on an unmade king-size bed.
C/c: a lemon and a lime cut in halves on a wooden chopping board with a kitchen knife to the right/a cup of cappuccino in a small café with the smell of coffee and the sound of clinking tableware around you at 7am.
D/d: a toddler in a knitted dark green sweater running to meet his father who just got home from work/a ballerina's foot spinning in pointe shoes as she pirouettes."
