LOL! What the hell, ya got them, play!
I imagine you are using 3 mm LEDs. The RGB are 5 mm with 1 cathode and 3 anodes.

A possible 7 colors. R (red), B (blue), G (green), RG (yellow), RB (purple), BG (lighter blue), RGB (white). An 8 position dip switch could be used if you wanted to just flip one switch or do a 4 position dip and flip R, G, B or any combo.
Just putting that out there if anybody wonders what you could do with RBG single LEDs for simpler spot lighting, not whole case. Intensity could come into play too...that makes my head hurt thinking of the possibilities.
