I've realized that there are certain color combinations I avoid because I associate them with something. Here are some off the top of my head:

1) Red, white and blue - USA Colors
2) Red and Yellow - Fast food, McDonalds
3) Red coats - Little red riding hood (even if there isn't a hood, I feel this association!)
4) Black and Yellow - Bumblebees

What color combinations do you avoid due to symbolism or association with something? I'm curious! =)
