It is recommended to use earth tone's eye shadow, because eyes with single eyelids generally give people the feeling of puffiness. If you use pink eye shadow, it will increase the feeling of eye edema. If you use dark eye shadow, such as earth tone, you can easily outline deep eyes, without giving people the feeling of puffiness, which will make your eyes bright visually. In addition, if earth tone is too boring to jump, you can add brown, just like a sunset plate.
