190 Chapter 6 Using Primatte

By using the foreground and background operators, you have assigned pixels to either

zone 1 or 4. Picking any of the eight operators assigns color to a different zone. The

following image is a chart of the operator/zone assignments.

This illustration demonstrates (roughly) how each operator dimples the surface of the

zones through the use of successive color picks. You may have seen implementations

of Primatte in other software using a real 3D representation of the color space using

polygons. While cool, only about three people on the planet seem to understand it.

Managing Operators

One swell thing about Shake’s implementation of Primatte is that you can review,

modify, or delete previous operators at any time. You do not have to start over from

illustration to review, modify, or delete previous operators.
