Just a little something to think about. Sometimes you want bright un-natural colors, it might be because you like happy colors, it might be so your gear stands out so you can find it, you may be less likely to have someone steal something that has bright colors. Also, if your colors are bright, you might be less likely to have some loaded hunter use your gear for target practice.
I use mainly muted colors, because I do not want to be seen. However, on my upcoming kayak trip, I will use a lot of bright Orange, so if something happens, maybe someone will spot me. Yin - Yang.
I think bears are color blind.
