Hello 
I m currently testing setting Clip Colors in Bitwig,
which is working fine outgoing from OSC/PILOT. It looks like this:
But when i want to receive Colors into OSC/PILOT to change the widget color, it doesnt work.
I tried different “custom in ARG” combinations like ? C C C , or just C
The incoming message has the rgb(x,x,x) format like this:
ADDRESS(/track/selected/clip/1/color) STRING(rgb(217,46,36))
Could you please help me making it work? 
Does my OSC/PILOT Color palette have to include every possible color in order for it to work?
