Adjust color
If you have optimized the tone reproduction, typically the only remaining color problem is a color cast—an imbalance in the colors of the image. Color settings affect the overall color balance and saturation.
Adjust color automatically
You can apply the Automatic preset to adjust color automatically.
Adjust color manually
You can adjust color manually without using a preset.
Temperature - Sets the blue-yellow color balance (the b channel in Lab color space).
Tint - Sets the red-green color balance (the a channel in Lab color space).
Saturation - Increases or decreases the saturation of all colors in an image.
Fleshtone Saturation - Increases or decreases the saturation of only fleshtones in an image, rather than the saturation of the entire image.
Lock (Saturation) - When selected, increasing or decreasing a Saturation setting increases or decreases other Saturation settings the same amount. For example, if Saturation is 10, Fleshtone Saturation is 20, and the lock is on, then increasing Saturation to 15 increases Fleshtone Saturation to 25 at the same time.
Auto (Color Balance) - Automatically corrects the color balance (temperature and tint) of the image to achieve the best appearance.
If the image is already optimized, or nearly optimized, you may not notice a difference. After you enable Auto, you can still fine-tune Color Balance settings, if desired.
