Hey... how did you develop the whole color coded spacial representation thing?

I'm not sure; my best guess is that it goes back to some childhood memory of letters/numbers represented in certain ways on various educational toys and the like.

In a similar manner, countries other than the U.S., and U.S. states, have associated colors in my mind, due I believe to a toy globe I had at a very young age. (Interestingly, however, I also have a memory of finding that globe again years later, and discovering that some of the colors were different from what I "remembered"!)
