Shorter light waves tend to be seen as orange and red.

Keegan notices that his favorite 55-cent candy bar seems lighter than usual, and so he checks the label and finds that it is lighter by ½ ounce. He decides to buy a larger candy bar instead and doesn't notice that the 99-cent candy bar also is lighter than it used to be by ½ ounce. Keegan's behavior illustrates the fact that:
