I've got three variables that I'd like to show as a red-green-blue composite map. It is easy enough to do this as a raster. I convert each attribute in the table to a raster and then create an RGB color composite. However, being able to view these data as polygons (or points) would be better because of the irregular boundaries and issues with scaling (i.e. I can give boundaries an identical color to the polygon interior to make them more visible or use points to represent especially small polygons). Is there an easy way to do this in the vector world? The only thing that I can think of is to go in and set the color for each individual polygon according to red, green, and blue columns.
