No. It distorts a pattern by moving each point by the value of the color 
vector of the displacing pigment at that point. The displacing pigment 
isn't used for colors, but for vectors. The rgb values are used for xyz 
values for translating the each point of the pattern being warped.
I am trying to figure out how to add a "vector_map" keyword, that would 
clear things up a little.
