I may have a very mild form of it. I don't see colors when I look at words, but I do associate colors with words and feel that certain letters and numbers and tones should be a particular color. I think I may have partially gotten it from this from this little alphabet-learning board I played with when I was very little, in which every letter was a different color. Some letters are more definitely a certain color than others. Like 9 - For the most part it's yellow/orange, but it isn't as far-fetched to see it as green than to see it as blue or something... 9 is definitely not blue. Some are definitely a certain color, like 3 is definitely green, it cannot be anything else. But 'H' isn't as certain. It can be green or purple or something.

The only time I've actually seen letters to be certain colors is in the case of the word Google, when it's presented in the same font as the Google logo. Without consciously memorizing the colors of each letter, I can tell what color each letter is because out of the corner of my eye I see the colors as those letters.

Also, I also see letters and numbers in a certain way when I imagine them, with certain positions relative to one another.

I feel like I've done this before on this site but this is how I see the alphabet whenever I imagine a letter:


A B C D E F G
H I J K L M N
O P Q R S T U
V W X Y Z


And numbers: 1 2 3 4 5 6 7 8 9

Now I have the ABCs song in my head.
