Color Utilities
Gamma Correct
Contrast
Use to increase or decrease the contrast
in a texture. You can control the contrast of each of the R, G,
and B channels individually.
When you increase Contrast,
light colors become lighter and dark colors darker. When you decrease
contrast, you bring all the colors closer to the middle range. The
Bias attribute
controls the center of this range.
Find this utility in
the Create Bar (see
Hide, resize or customize the Create bar).
To use this utility,
see
Use the Contrast utility.
