You can make slight or massive changes in the color of your photos. A picture with cool colors and a bluish cast can be turned into a warmer photo with a slight reddish tone, for example. Making subtle but important color corrections can take a while to master.

This setting changes the overall color of the entire picture. If the overall color is off or the color of the light gives the photograph an orange or bluish tone, use the hue adjustment to change this. It is especially useful for making white balance corrections. You can adjust the hue in very small increments, so getting to the right color can be quite a precise operation.

Saturation refers to the intensity of the color. Bright bold colors, for example, are highly saturated. While highly saturated images can be eye-grabbing, they are rarely natural. Make this adjustment carefully and don't get carried away.

The lightness control adds white to the color when it lightens the pictures and adds black to the color when it darkens the picture.

Many programs allow you to adjust the colors separately. They are usually adjusted on a sliding scale. The RGB has three controls: Red, Green, and Blue. The CMYK control has four: Cyan, Magenta, Yellow, and blacK. This control is difficult to learn because it takes a lot of experience to understand the settings or mix of CMYK that produce a certain color or color cast.
