# Color Balance

Keep the colors in line.

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.
