Re: [Update REQ 6003]: dithering

We are trying to use Geomview with out finite element package. A common use will be to 
shade inside the elements in order to represent the varying quantities. Now I have a 
question :

Is it possible to creat a color map which goes from 0 to 1, such that

 at 0.0,   R=0, G=0, B=1  --> Blue
 at 0.25   R=0, G=1, B=1  --> Light Blue
 at 0.5    R=0, G=1, B=0  --> Green
 at 0.75   R=1, G=1, B=0  --> Yellow
 at 1.0    R=1, G=0, B=0  --> Red

if I can utilize such a color map to shade polygons, a major problem is solve for us.

               Thank you.
