Green screen remover

Chroma keying matches hue rather than overall colour. That matters because a lit screen runs from near-white at the top to nearly black in the shadows — enormously different as colours, almost identical in hue.
What it does
- Keys on hue, so the whole screen goes even when it is unevenly lit.
- Saturation and brightness floors protect dark hair and grey clothing.
- Spill suppression pulls the green cast out of the subject.
- Works on blue and any other screen colour, not only green.
The part most tools get wrong
Spill, and the floors that protect the subject. Light bouncing off a green screen tints the subject's shoulders and hair; removing the screen does not remove that cast. And a hue-only key with no brightness floor eats black hair, because a nearly black pixel has an unstable hue that can land anywhere. Both are handled here.
Common questions
My subject has a green rim. How do I fix it?
Set "Neutralise colour cast" to green spill. It caps the green channel at the average of red and blue wherever green dominates, which removes the cast without touching anything legitimately green.
Does it have to be green?
No. Pick any screen colour with the eyedropper. Blue screens are standard where the subject wears green, and the keying works the same way.
Why is my dark hair disappearing?
That is the brightness floor being set too generously by a large tolerance. Lower the tolerance; near-black pixels then fall below the floor and are kept regardless of hue.
