ELI5: Why do hunters bother with camo when they always wear bright orange?
gpt
Deer are color-blind. They see shapes and movement more than bright colours, particularly when those shapes have a regular or plain pattern and are showing in relief against a background that doesn't look like them, which most non-camo jackets and pants have a tendency to appear like.

Even if it's just on the arms and legs because a fluorescent vest is being worn over the chest, the camo helps break up the outline of the hunter against a background of leaves or branches or bushes, while the orange provides high visibility to other hunters or search-and-rescue parties.
