Generate Particles with Random colors (continuously or from a set) I am trying to do rocks and I want them to have a random base color from within the colors that look "rocky". The only method I know of is to duplicate the base objects over and over and give each a different color in the node editor, then group them all and use them as the group input for the particles. This is slow, inefficient to change, duplicates a lot of data, and comes out with a uniform distribution of the colors. Is there a way to have give particles a random color from a set or range?
I'm going to keep this short and simple. Do everything Duane Dibbley did but use an Object Info node instead of a Particle Info node. Connect the random output directly to the color ramp, no math node needed. 



Pro Tip: Make sure that if you are using a color ramp set to constant that you don't put any colors at position 1 (all the way to the right). They won't end up being used.
