Small hint: Control three colors with a DX300, and figure out the fourth color from the other three.

Big hint: At any given time, the DX300 is either in input mode or output mode, which is a bummer. However, an OR gate or a NOT gate is a way around that.

Optimization tip: Control the lights during different time intervals with different microcontrollers. This will make you use some rather unusual parameters for the slp command, such as

slp 12 slp 21 slp 36
