Depending on what lights you are using, you can buy coloured filters that go over the front, changing the light colour. I'm not sure if you can really substitute any of them colours.

 

Wrong section. Belongs here http://www.sythe.org/forumdisplay.php?f=295

It could be any of 2, 3 or 4 though. Depends on the lights type.
