Hi

Does anyone have info or circuits for getting more than 7 colors from a RGB led?
Also I DO NOT want to use a micro processor/controller!
Maybe PWM or ? I have a circuit that does 7 colors, but I would really like 256 or more.

Thanks all
 

You can use op-amp based PWM generators to make your mood light. Check out this schematic. You may need to adjust R1, R6, R14 for your LED type. Colors can be changed using VR1, VR2 and VR3.
