Why are female birds so dull-colored?

This is a universal question that not only girls ask but boys ask. Why do female birds have such dull feathers, and why are the males the most colorful? Well, the males use their colors to show off to the ladies, mainly to find a mate. Peacocks, birds-of-paradise, hummingbirds, and many more male birds are brightly colored. When a female lays eggs, she uses her brown and tan feathers to blend in with her background when she sits on her eggs. That way, predators won't easily notice her, her nest, and eggs.
