Body gives them colors
Animals' body parts，like feathers，hair and skin，have special structure.They reflect（反射） light to make animals colorful.This is called structural color（结构色）.For example，blue butterflies have fancy scales（鳞片） on their wings.This gives them a bright blue color.Structural colors don't fade（褪色）.People use the idea to make special clothes and paints.
