The color_correct node allows you to adjust the gamma, hue, saturation, contrast, and exposure of an image. Alters the Input color with the following operator, applied in the same order as the parameters.

Input

Input color to apply the color correction to.

Alpha is Luminance

Ignore the input alpha, setting the output alpha to the luminance of the RGB color.

Alpha Multiply

Multiply the output alpha with a factor.

Alpha Add

Add a value to the output alpha.

Invert

Invert the input RGB color.

Invert Alpha

Invert the input alpha.

Gamma

Applies a gamma correction to the color.

Hue Shift

Rotates the color hue, a value of 1 means a full rotation. 

Saturation

Scale the saturation by this factor.

Contrast

Scales values around the Contrast Pivot

Contrast Pivot

The origin of the contrast scaling. The default is 0.18 which is the average perceptual mid-gray.

Exposure

Multiplies the color using a photo f-stop scale, where an increment of 1 doubles the luminosity.

Multiply

Multiply the color by this factor.

Add

Adds this value to the color.

Mask

Blends between the Input color and the color corrected one.
