RGB LED

Red Green and Blue LEDs all rolled into one beautiful package! They come in common anode and common cathode varieties. You can find them at tons of electronics stores like adafruit, and sparkfun, for example. Using pulse width modulation you can get a beautiful spectrum of colors. Or just doing different combinations of Red Green and Blue you can get 3! = 6 different colors. Because n factorial equals the number of permutations of n things.
