Jimbo,
IF you can't outrun them, you need to outsmart them.
Bears can see colors like humans, but don't see reds and oranges very well. I'm thinking PINK falls in there somewhere. ;) ;D ;D

Bears see color very well. We can tell this by the number and position of the rods and cones in their eyes. Rods collect light, and cones interpret color. Bears particularly see colors on the blue end of the spectrum very well. They may not see reds as well as we do, but definitely better than deer. Deer see blues and greens especially well, but do not see reds well at all. In fact, if you go into the woods wearing a blaze-orange shirt and blue jeans, a deer can pick out the blue better than you can, but can see the orange only as subdued tones. The orange would be barely visible but the blue would glow like the fluorescent orange does to our eyes! Bears are not that extreme, but they do not see reds and oranges very well.
