Chroma Key Green — the studio green screen standard
Green is the default key for most video work: it's the brightest channel on a digital sensor, so you need less light and get the strongest signal back. Chroma Key Green (5711) is the purpose-made, ultra-matte green that keys clean in two coats and stays consistent for years.
Is green your key?
When green is the right key
Green is the everyday choice — here's when it's clearly the one to build.
General video & broadcast
The most common key: strongest on the camera's green channel, easiest to light.
Little green in shot
Your wardrobe, props and set have minimal green to conflict with the key.
Lower light budget
Green returns the most keyable signal, so you can expose the wall with less light.
Problems it solves
The green-screen problems it solves
The complaints shooters keep posting — and why 5711 doesn't have them.
Four coats and still patchy
Low-pigment greens build slowly and read uneven.
Green spill & noisy edges
Off-target green spills onto talent and dirties edges.
Hot spots under the wash
Sheen throws glare that breaks the key.
Touch-ups show
Different batches key differently.

Application
Lay it down right
Green is forgiving to light, but the wall still has to be even and matte. Prime, two coats, light it flat.
Prep the surface
Clean, dry, oil-free. Fill and sand — even light reveals every defect.
Prime porous areas
Roll Tough Prime White for a uniform base so colour lays even across a big wall.
Stir, don't shake
Stir until uniform. Use straight from the tin; thin only minimally if at all.
Two even coats
Brush, roller or spray. Keep a wet edge and overlap strokes. Two coats over primer.
Recoat, then cure
Touch-dry in ~30 min, recoat in 1–2 hr, so both coats go on in a day.
Light it evenly & test
Even wash, no shiny props or floor spill — then check the key on your camera.
