You don’t find ugly color combinations in nature. I think that’s because our sense of beauty comes from the natural world. But why? Why do we find sunsets beautiful? It’s probably due to the bright colors. Why do we love bright colors? One explanation would be that we love bright colors in order to be attracted to ripe fruit. The sunset is just God’s way of reminding us to eat more fruit. Pollen collecting insects are also attracted to bright colors, so we share our sense of beauty with insects.
