RGB curves - Why does adjusting the G curve also result in a change in R and B channels?

[heckflosse (Ingo Weyrich)]

@sovereign

I did something similar in non-luminosity blending mode, don’t compare the values with the previous post:

R: 27,1 −−−−→63,9 -----> 63,9
G: 51,0 −−−−→45,5 -----> 45,5
B: 85,1 −−−−→78,4 -----> 78,4

Closer, but they do change.
