Corel Painter has a variety of effects that let you adjust color and tone. Some effects are designed primarily for correcting colors, while others let you adjust colors for special effects. For example, you can match colors across images, invert colors, or posterized colors.
You can also use tools, such as the Dodge tool and the Burn tool, to adjust color and tone in specific areas.
For information about color correction, see Correcting and Adjusting Colors.
The Match Palette effect lets you apply the color and brightness of a source image to a destination image. For example, you can match the colors in a photo to the colors in a favorite painting. You can then clone and paint your photo in the same style as your favorite painting. You can also use the Match Palette effect to ensure that the color and brightness in a group of photos is consistent.
You can apply the color and brightness from a source image (centre) to your working image (left) to create a new effect (right).

the colors in the destination image. At higher settings, more source color is
applied.

Variance (Color) — lets you adjust the range of the source colors. Higher
settings increase the number of shades used from the source image.
|

Brightness — lets you determine how the luminance from the source image
blends with the luminance in the destination image. Higher Brightness settings
pull more highlights and shadows from the source image into the destination
image.

Corel Painter can posterize your image based on a color set. This effect lets you create an image with only a specified set of colors in it. This is useful for multimedia work, as well as applications such as silkscreening.
This effect can also be used to reduce an image’s colors so that the image appears correctly on the Web. For more information, refer to Working with Posterize Using Color Set.
