The “With luminance level preserved” checkbox, which is on by default, keeps any channel adjustment
you make from altering the luma of the image by automatically raising or lowering the other two
channels to compensate. In the following example, you can see when “With luminance level preserved”
turned on, lowering the Green control group’s Green slider results in the red and blue channels being
raised by the same amount as seen in the Parade scope. Conversely, raising a color channel’s slider ends
up lowering the other two channels by the same amount to keep overall image luminosity the same.
If you Right-click anywhere within the RGB Mixer while in Color mode, a shortcut menu appears with
four commands:
Reset: Resets all sliders to their default positions (Red = 100 for red, Green = 100
for green, Blue = 100 for blue, and all other sliders = 0).
Swap Red and Green: Swaps these two color channels.
Swap Green and Blue: Swaps these two color channels.
Swap Red and Blue: Swaps these two color channels.
At top, the original image. At bottom, the result of an RGB Mixer adjustment with “With luminance level preserved”
turned on. You can see that lowering the green channel slider also raises red and blue.
