How chroma keying actually works
Why green and blue specifically
Human skin contains almost no green or strong blue, so those hues are the furthest from a subject in colour terms. That gap is the whole trick: it lets a machine separate foreground from background by colour alone with very little risk of eating the person.
A lit screen is never one value
Real screens have hot spots, falloff at the edges, and shadow where the subject blocks the light. That is why the tolerance starts at 45 rather than the 20 a flat graphic needs — you are matching a range of greens, not one.
Green spill on the subject
Light bouncing off the screen tints hair, shoulders and light clothing green. A tolerance high enough to clear the screen will start eating those edges. If you see the subject dissolving before the screen is gone, the original lighting is the problem and no key setting will fully rescue it.
Avoid green in the frame
Anything green on the subject disappears with the background. That is the classic reason a presenter never wears green in front of a green screen — and if the wardrobe is green, switch to a blue screen instead.
Stills only, and PNG out
This works on single images rather than video. The output is PNG because transparency needs an alpha channel, and re-saving as JPG would fill the keyed area back in with white.
How to remove a green screen
Upload the still
Drop in a frame grab or photo shot against a green or blue screen.
Tune the key
The default is broadcast chroma green. Adjust the colour to match your screen, then raise tolerance until the background clears without eating the subject edges.

Where green screen removal is used
Frame grabs
Pull a keyed still out of green screen footage for a thumbnail or a poster.
Studio portraits
Cut a subject shot against a coloured backdrop free of it.
Product shots
Key out a coloured sweep so a product sits on any page background.
Presenter cut-outs
Place a speaker over slides without the studio wall behind them.
Or just ask
Describe the edit in your own words
Type what you want changed and the assistant does it on the canvas — each step lands as a layer you can reopen, so nothing it does is baked in.
