This site is amazing. And, wildly confusing! Ha ha, there are so many things that go into determing the colors. Wow. Anyway, I thought with the interesting little debate going on in this otherwise undebatable thread, I might just post this link. I've been reading a lot of the stuff about chestnut and sorrel (they are the same, which is kinda what I thought), and, started reading about the modifiers and all that other stuff. Just thought I'd specifically share the page about "bay", but, the other pages are interesting too if anyone wants to check them out. Cool stuff.
