There are so many ways to use the Prisma pencils that don't require the Gamsol. The first is just of course to color - select three different variations of a color and just play with layering one color on top of the next. Many of the images in my gallery on my blog are colored this way. The colorless blender pencil works beautifully for smoothing out your colors and the Prisma clear blender does work similar to the Gamsol on your color images as well. I have a section of my blog (green link below) dedicated to color pencil techniques. When you arrive at my blog - look at the categories section on the left and click on the "Tips and Techniques" section. Then scroll down that page until you arrive at the color pencil information. I hope this helps
