Separately editing one color curve on Curves-custom page.

Hi, everybody!
I'd like edit one color curve on Color/Curves-custom page. But if I change something in red curve there are a small changes in green and blue curves. Is it possible to edit only one color without editing another color?

Change the luminance mix setting from 100 to 0. This turns off the Y channel of BMs YRGB system. It can be found in the lower right corner of the primaries palette.

Thank you! Already tried this. Do not work. DR 19 beta 3

Luma Mix reduces how much other channels are affected, but it doesn't entirely eliminate it.

Should it? Or is this a beta bug?

would this work for you ? I tried it once and using levels ( lift gamma gain) and saturation, etc. I was able to affect the rgb colors separately.

Thank you! I know about this.

another thing you probably already know about is turning on log. when you visualize rgb as roman arches that overlap each other, and then turn on log the arches overlap each other much less.... meaning the influence of one color effects the other color much less....

Thank you! Yes, I've tried this already.

This works for me. If you enable the Parade scopes you will see that the Individual curve adjustment will no longer affect the other channels. Of course the Y channel will change as it is a sum of the other channels.

What are your colour management settings? This will affect the RGB channel behaviour too!

This works for me in 18.6 windows. Perhaps you have nodes in the chain after the curves that cause the other channels to become affected when there is a change,

I didn't mean the y channel wouldn't change. I mean it turns off the ability to adjust the y channel. Resolve works in a yrgb system which is why a change to one color channel changes the others. Turning the luminance mix setting to 0 turns those primary adjustments to rgb only.

I use only one node.

Does not work in DR 18.6 in my case.

It is likely that you have a setting somewhere causing this problem. I have never seen this issue in many years of using Resolve.

Here's a video showing it working on R19b3.

Thank you very much to all! I understand at last.
