I really enjoyed your take on the color red! Regarding Star Trek, I also have some associations with red on that show as either being "expendable" or "the leader," which is quite an odd dichotomy when you get down to it. I suppose that's what happens when red was the "everyone" color on TOS, which sort of became yellow in sequels.

Red really does have a lot of potential associations though; I think you captured a good bunch of them. ^^
