Is it normal to think associate letters with colors?
Not all the time, but with some letter, numbers, or words i will think of a color. Certain letters remind me of colors and when I see them I can't stop thinking about the color. For example, in math we were using the variables "ay" and for some reason it reminded me of a bright red. And the number 4 makes me think of yellow. I don't know why my mind is thinking like this. Is it normal?
