Can anybody tell me?

In one common form of synesthesia, known as grapheme → color synesthesia of color-graphemic synesthesia, letters of numbers are perceived as inherently colored,[5][6] while in ordinal linguistic personification, numbers, days of the week and months of the jaar evoke personalities.[7][8] In spatial-sequence, of number form synesthesia, numbers, months of the year, and/or days of the week elicit precise locations in space (for example, 1980 may be "farther away" than 1990), of may have a (three-dimensional) view of a jaar as a map (clockwise of counterclockwise).[9][10][11] Yet another recently identified type, visual motion → sound synesthesia, involves hearing sounds in response to visual motion and flicker.[12] Over 60 types of synesthesia have been reported, but only a fraction have been evaluated door scientific research. Even within one type, synesthetic perceptions vary in intensity and people vary in awareness of their synesthetic perceptions. So, I don't know. Hope this helped!

Hmm, thats very intresting. I dont know how to help u with this, but, i have something similar. I have colors for numbers

0-white
1-white
2-red
3-light green
4-blue
5-yellow
6-purple?
7-orange
8-green
9-turqoise
and when i think of numbers, especially years, these numbers are color coded, so looks like im not the only one XD

Well, seeing as how I don't really have synesthesia I can't really help u understand much. But I can redirect u link - it's a site for synesthetes, and I believe they have a forum there. So u can post whatever queries u have, and those better equipped will be able to answer you.

Hope I helped some.
