I set up a new color ramp for contouring. I want to show drawdown values: blue for positive values, red for negative values and white to zero value. Is it possible to assign no color to the zero values so that I can see the raster map under the contouring layer? My workaround was to save GMS project to image file, open it in Quantum GIS and set the transparent color to white. Thank you Daniele
