# Color Balance

Color Balance is used to tune the appearance of colors in an image. This can correct for imperfections, or you can use it to create dramatic effects.

**Shadows, Midtones, Highlights**\
Select the tonal range that will be used when adjusting the color balance. There is some overlap in these ranges to keep the image looking natural.

**Cyan / Red, Magenta / Green, Yellow / Blue**\
Move these sliders (or use the edit boxes) to add or subtract colors from the image.

**Preserve luminance**\
When this is checked, the overall luminance of the image will not be changed. In most cases it is good to leave this checked to keep the overall tonal balance.
