I have this. Every letter and the numbers up to 20 have individual colors, then the 20s are yellow, the thirties are gray, the 40s are red, 50s blue, and so on, then in the hundreds it turns to white and all numbers are white. Days of the week and months have colors. Decades of history have colors. Like the 1700s are all green but the 1960s are red and the 1970s are a different shade of green. Some individual words have colors, usually with what they represent. So egg is white and elephant is gray. But museum is dark red which doesn’t really align with anything. I don’t have any color associations with sound or music. I don’t think this has changed my life whatsoever. I thought everyone did this until I was a teenager and mentioned how the letter A was a red letter and no one knew what I meant. I can’t speak on artists or musicians saying it is like a superpower. I think it may help me remember things better, although I don’t have an extremely good memory.
