Say, your b-factor values range from 0-10, and your object is called "protein", then you could do: color white, protein color yellow, protein & b > 2.5 color orange, protein & b > 5.0 color red, protein & b > 7.5 If you want to automate that process, then you need to write a script that determines, the b-factor limits for the 4 colours based on the b-factors present in your structure.
