Introduction to the RGB Mixer Palette
The RGB Mixer palette lets you remix different amounts of image data from one channel to another, and has a wide variety of creative and utilitarian uses. Furthermore, the RGB Mixer can be used either to remix the color channels, or to add different proportions of each color channel into a monochrome image.
RGB Mixer palette
By default, the RGB Mixer palette is set to mix any amount of the Red, Green, and Blue color channels into any of the other channels. Each color channel has a dedicated control group of Red, Green,
and Blue sliders that you use to do the mixing, and the default values of these can be seen in the screenshot above.
Each slider has an overall range of –2.00 to +2.00. This means that you also have the option of subtracting any combination of color channel values from a particular channel. For example, you can lower the Red control group’s Green slider to –.24 to subtract 24 percent of the Green channel from the Red channel.
