The Color Balance adjustment provides a way to modify the contribution of particular colors to a set tonal range.
Settings
Apply this adjustment via the Adjustments panel using the following settings:
Range—determines the tones to be adjusted.
The sliders control the balance between the two named colors. Drag the slider toward the color you wish to emphasize.
Opacity—sets the level of visibility of the adjustment.
Preserve Lum.—if this option is off (default), the adjustment ignores the original lightness value of pixels. When selected, the adjustment modifies pixel colors with respect to their original lightness value.
Merge—merges the current adjustment layer with the layer immediately below it in the layer order.
Delete—closes the settings and deletes the adjustment layer, removing the adjustment.
Reset—reverts all adjustment settings to default.
Add Preset—adds the current adjustment settings as a preset for use with later images and projects.
