This comes up a lot with my dad, who is a teacher, so a lot of his materials are color-coded. If he chooses the wrong color folder for materials for a certain day of the week or something, it will bother me until I snap: "YOU CAN'T MAKE WEDNESDAY GREEN, DAD, WEDNESDAY IS YELLOW," and he's like, "I just needed a Wednesday folder and I happen to have a green one -- what's the big deal?" But it's like making a stop sign blue -- you can't really articulate why it's wrong, it's just incredibly wrong.

This can actually create arguments between synesthetes. (Yes, we do hang out together in roving gangs, occasionally getting into dance fights with the projectors.) Amazingly, there's actually a large degree of agreement between synesthetes (and even non-synesthetes) when it comes to what color things should be. For example, most people agree with me that the letter A is red. In fact, there appears to be a universal color scheme that almost everyone agrees upon for about half of the alphabet, and no one's really sure why. However, associations can be unique to the individual synesthete. So, like, one of my friends perceives Mondays as blue and Tuesdays as red, but it's the opposite for me, and I will absolutely throw down with that bitch about it. (Not really, girl, you know I love you, but put that folder back. Put it back. Put it back before I cut you.)
