Class: ColorMatrix

Phaser.Display. ColorMatrix

The ColorMatrix class creates a 5x4 matrix that can be used in shaders and graphics operations. It provides methods required to modify the color values, such as adjusting the brightness, setting a sepia tone, hue rotation and more.

Use the method getData to return a Float32Array containing the current color values.
