In the LIft Gamma Gain color correction effect, Lift behaves differently than Gamma and Gain.
If the slider is left in the default position, the color selector has no affect.
I the slider is pulled down the color selector behaves as if inverted ie pushing toward red increases cyan.
If the slider is raised, the color selector behaves as expected -ie pushing toward red increases red

This behavior is different than Gamma and Gain, is there a reason for this?

Thanks

It is the same with me. (Manjaro Linux, Kdenlive 20.12.2)
If the slider (B: 0,000) is left, the color selection has no effect. If you close the eye and open it again (Disable Effect - Enable Effect), the color selector jumps back to the center. But only with Lift. For Gamma and Gain the setting remains.
