Suggestion: when compositing photos from rgb channels, red should consume cyan, green should consume magenta, and blue should consume yellow.

The point is that because what is "no light" and "light" in photography becomes "ink" and "no ink" respectively (notice how the status of being empty is flipped) red channel becomes the cyan channel, green becomes the magenta, blue becomes the yellow.

As a more concrete example, below is a table of what the rgb channels would look like for different colors

color R G B
red 1 0 0
yellow 1 1 0
green 0 1 0
cyan 0 1 1
blue 0 0 1
magenta 1 0 1
black 0 0 0
white 1 1 1

heres what cmy channels would look like

color C M Y
red 0 1 1
yellow 0 0 1
green 1 0 1
cyan 1 0 0
blue 1 1 0
magenta 0 1 0
black 1 1 1
white 0 0 0

notice how RGB correspond to CMY respectively, with values flipped.

This is like a nitpick more than anything but im autistic about it id love to see this fixed cause its inaccurate

I not sure about this.
The mod is not meant to be realistic in every way and printing probably the main example here (hence why it's called Lightroom, as it's more of an opposite process to real life).
I'll think about this more later, maybe changing it would be better, idk.

Config options to change what dyes are consumed for each printing process are added in 1.21.1-1.8.0.
