Hmm... so is this related to memory only?
I honestly don't know, but the fact many people see "a" as red, me included, seems strange.
Do you actually perceive colours overlapping text or do you associate the memory of letters and numbers to colours?
Voyels and numbers are very strongly colorful (it covers the letters and "bleeds out") while the other letters are more like monochrome (ok not really monochrome, but less intense at least, it doesn't influence the letters (or symbols) around them).
Actually, once I was curious to try to see what would happen with non-latin languages like chinese and thai, and even if the colors are much less intense (maybe because I have no clue what words/symbols woulds mean), I can still sense a pattern: without thinking, there is color there, but I think the sound is a factor to the strength of the color (unrelated [well, not that I noticed at least] to music-induced colors).
On the other hand, I am used to try to repress paying too much attention to it because I spend 99% of my awake time looking at text (programming ftw) [so syntax highlighting colors make more sense profesionnally than my natural colors], though I feel very confortable with pages and pages of black & white code because the colors somehow "make sense" while my collegue go crazy over the walls of text.
Now, a person who has a car accident because a guitar riff paints his vision in bright orange, that's just cool.
Haha
Edit:
One boring evening, I went ahead and made a map of the alphabet: http://photos-g.ak.fbcdn.net/hphotos-ak-snc1/hs005.snc1/4162_76332802437_828317437_1687531_6189987_n.jpg (facebook photo, I hope the link works nontheless) where plain letters represents colors that bleed out and outlined letter means color that are there but don' influence their neighbourgs. I really should add numbers to that one day however as, unlkoe letter, they all strongly bleed out.
