not only one tracyh, i get synaesthesia with words and numbers and colours..[and i also have red/green colour blindness; it is interesting to check your colour loyalty; write down the alphabet and name the colour of each letter, also days of the week, numbers etc. Leave it for a month, then write out another list and compare; you may find that you are very loyal to certain combinations and not others, my yellow always associates with F, M, Monday, Friday, and 8 although the eight is a more creamy yellow.. yeah, quite mad. :-)
