Colors are simply our brains' interpretations of light as it is absorbed, reflected, or refracted by objects and bounced into our peepers. The human eye can differentiate between 30 shades of gray and some can see over 100 million unique colors—which is impressive only if you're not a mantis shrimp, which can distinguish four times the number of hues.

Put another way: color is freaking neat. If you're not embracing the magnificence that is the many-hued home, you're missing out on raw joy. Below, a few colorful items to make your life a bit brighter.
