Correcting colors using curves
Corel Painter lets you correct colors by using curves to adjust the relative amounts of
the color components in an image. You can adjust the curves for red, green, blue, or all
three color components at once. Modifying a curve individually is useful for correcting
an unwanted color cast. The curves describe how the input color values are adjusted to
create the output (corrected) color values.
