Abandoning color grabbing in color mixer

Browse source 
We'll end up with things like "132/245 red, 90/245 yellow, 23/245 blue".
Getting it to work will likely require some massive brute-forcing.
If people want to take an existing color and make subtle changes, they
can just use the rainbow palette HSV color picker.
