 Adrian Bonsanger. I do know that there is a name for seeing numbers as colours, and it's called synesthesia. Have either of you come across this? I have heard this before. Meral, do you know what it is? It's a neurological phenomenon where you kind of blend the senses. So number, colour, synesthesia, you see the numbers, so six will always be green or whatever the link is in your head. Is that something, Meral, that you've seen before?
