These functions perform modifications to the texture's colors, like increasing the brightness, shifting the hue or changing saturation and contrast.

Overview of the Color functions group:

	Amplify	HSV amplification and transformation.
	Apply Gradient	Convert grayscale values to a colorful gradient.
	Black and White	Dark colors become black, others white.
	Boost	RGB amplification.
	Brightness	Lighten and darken by a fixed value.
	Color Delta	Distance to a color become grayscale values.
	Contrast	Change the texture's contrast.
	Convert	Set hue, saturation or brightness to a fixed value.
	Exchange	Switch two RGB or HSV channels.
	HSV Transformation	All the HSV modifications you can imagine.
	Invert	Negate a RGB color channel.
	Maximize	Set the texture's contrast to maximum.
	Quantize	Round the color to fixed levels.
	RGB Transformation	All the RGB modifications you can imagine.
	Saturation	Increase or decrease the saturation.
	Shift Hue	Change the hues, but maintain their relations.
	Synchronize	Adjust the colors to another texture.
	Threshold	Set the color channels to minimum or maximum.
