In order to get from fully black to cyan you expect the ramp to pass by solid blue? It makes some sense, but not sure how that could be coded. What you get is the simplest color ramp implementation, linearly interpolate all color component from first to second color. Getting a random gradient generator from the net you get exactly the same behavior: http://tools.dynamicdrive.com/gradient/ If you want to go through blue you have to configure it as the value for 0, then you'll get from white to solid black to solid blue, and then from blue to cyan. Out of curiosity, what kind of application generates gradients the way you'd expect? Cheers Andrea -- ------------------------------------------------------- Ing. Andrea Aime GeoSolutions S.A.S.
