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.

A visual representation of the curve.

The horizontal axis represents the input (original color) values. The vertical axis represents the output

(corrected) values. Before you adjust a curve, it appears perfectly diagonally (45°), which indicates that all

input and output values are equal. Corel Painter maps light values at the top of the graph and darker values

at the bottom. When you edit RGB curves, the current color is indicated by a colored point on the curve. For

example, if you’re editing the color blue, dragging the curve below the diagonal line subtracts blue from

the image and adds its complimentary color yellow. Alternatively, dragging above the line intensifies the

color blue.

You can use any of the following curve methods to correct colors:

• Curve

• Freehand

• Advanced
