Channel Mixer

Remix red, green and blue contributions for creative colour grading.

Colour film and video store red, green and blue as separate channels. A channel mixer lets you rebuild luminance and hue by weighting those contributions, the way darkroom printers filtered enlargers and the way cinema colourists reshape a look without a full grade.

It is a precise tool for mono conversions and creative colour breaks. Small shifts can warm skin or cool shadows without a blunt temperature slider.
