	This tab contains ~~four sliders~~ for manipulating the values from the Main input.		This tab contains settings for manipulating the colour values from the Main input. Use the “Black point” slider to define the colour value you wish to be the lowest value and the “White point” slider to define the colour value you wish to be used as the highest values. Values can extend beyond 0 and 1.

	~~Use the “Black point” slider to remap the lowest (black) values and the “White point” slider to remap the highest (white) values. Values can extend beyond 0 and 1.~~

	~~The value displayed from~~ the ~~sliders with a colour picker button to their right represent~~ the ~~largest of the three RGB components that make up the color~~.		In the example images below this Power fractal pattern was used as the source texture.

	The sliders without the colour picker button are “median” sliders, that is their value represents the middle value of the three RGB components when placed in order from smallest to largest. This allows you to shift the colours up or down without changing the spacing of the RGB values within the colour, which is helpful when dealing with negative black points. This value is expressed in linear sRGB.
