Scripts:
s@myColor = "color_"+itoa(rint(@Cd.r*255))+itoa(rint(@Cd.b*255))+itoa(rint(@Cd.g*255));
Watch how you can use paint to create parts and use this attribute to split geometry into pieces. But why? Easy to create groups on complicated geometry (compared to traditional selection) and you are guaranteed no group conflicts because there can be only one color on the geometry. Also, I am going quite in-depth explaining why traditional attribute promote does not do the trick.
