3 Adding 1 to each channel keeps the inversion but moves the values back into a
positive range.
Example 2: Brightness per Channel
This example influences the brightness of each channel individually. This subtracts 0.2 from the
red channel, adds 0.314 to the green channel, and adds 0.75 to the blue channel, while keeping
Alpha as it is.
Example 3: Copying Values
You can also copy color values back and forth between individual channels. In this example, the
red channel contains the luminance values of the image based on thirds, and the green channel
contains the luminance values based on the proper black-and-white conversion method,
whereas the blue channel uses a third method based on getting more information from red and
less from blue. The blue channel’s brightness is also lowered by 0.1, and the Alpha channel is
replaced with the original blue channel.
Settings Tab
The Settings tab in the Inspector is also duplicated in other Color nodes. These common
controls are described in detail at the end of this chapter in “The Common Controls” section.
