LEDs can be assorted colors or all the same color, you decide. You can get LEDs from almost any electronic store like Radio Shack or online. Colors are a personal preference and dont really matter. I had some spare ones laying around, but next time I think I will use these cool Purple LEDs from Allied Electronics.
