Color controls set the colors for different color
components. You can set the color by clicking the
color swatch to display the
ColorSelector(page
1–157)
.
Note: The Metal shader does not have a Specular
component, because it generates the specular color
automatically. The Multi-Layer shader can have
two different Specular color components, so for
this material the Specular color swatches are found
in the Specular High lig hts group. The Strauss
shader has only a single color component, which
corresponds to Diffuse.
1. Specu lar color
2. Diffuse color
3. Ambient color
