RGB Mixer Tab
The RGB Mixer lets you remix different amounts of image data from one channel to another, to
accommodate a wide variety of creative and utilitarian uses. Furthermore, the RGB Mixer can be used
to remix the color channels, or used to mix the color channels into a monochrome image.
By default, the RGB Mixer 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
Each slider has an overall range of -200 to +200. 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.
