 		 #176495 - Use another look-up table...
Responding to: ???'s previous message
Chico said:
Ok this works beu when R reachs value 4, the next step would be B=1 R=0, so a not smooth transition.

So, you want to increment or decrement COLORVAR and by this create a sequence of changing colors?

I would store a suited sequence of changing colors in an additional look-up table:

1. 300
2. 400
3. suited color that fits to 400
4. ...
