Warm light bulbs vs cool light bulbs: Which should you buy?

When replacing light bulbs around your home, you may not put a ton of thought into which bulbs you buy beyond wattage. More specifically, you may overlook the color temperature of the bulbs -- or maybe you pick one color over the other because you prefer it. The fact of the matter is, the color of the lights you install matters. Different colors have different functions and you should be paying attention to where you install those colors.
