Secondary Color Correction with levels or curves

[dparsons85]

I really dislike that I only have a few options when it comes to secondary color correction through the Lumetri Color effect. What do you do when you want to apply curves though secondary color correction? Recently I've been duplicating the clip, keying they color, reversing the alpha, and then applying a curves effect.

Let me know if you have a different solution. Thanks!

use another instance of lumetri and use the compositing options of the effect to target a mask.

Thanks Roei! I did something similar to your suggestion. I made the selection with the HSL Secondary in the Lumetri Color effect, changed it's mask to Black/White, and then used that as a luma track matte for another clip that had the curves effect I wanted for that section.
