Introduction

This shader allows you to apply various color correction math. It is useful for tweaking colors or applying user-defined gamma correction curves.

Parameters

Input

This is the color that will be corrected.

Gamma

This is the gamma value to apply to the color components. A value of 1.0 means no gamma correction is applied.

Contrast

This is the contrast adjustment value to apply to the color components. A value of 0.5 means no contrast adjustment. Values less than 0.5 will reduce contrast, while values greater than 0.5 will increase contrast.

Hue Shift

This is the hue shift value between 0 and 1, where 0 represents no color shift and 1 represents 360 degree hue color shift.

Saturation Scale

This value scales the color saturation. A value of 0 means no color saturation, gray-scale.

Level Scale

This value scales the brightness of the color, while maintaining the same hue and saturation. A value of 0 means the color will be black.
