Rosco Chroma Key Paint — Green & Blue Screen
Rosco keying paint · Chroma Key
Rosco Chroma Key — the studio keying standard
The purpose-made keying paint that broadcast, education and content studios around the world build their green and blue screens on. High-saturation single-source pigment, an ultra-matte finish, and an even, keyable wall in two coats — not the three or four a thin hardware-store green needs.
Built for real keying problems
The keying headaches — and how Chroma Key ends them
Straight from what studios and shooters actually complain about online. These aren't house-paint problems; they're the reasons a generic “chroma” tin still gives you a dirty key.
“It took four coats and still looked patchy”
Thin, low-pigment paints build colour slowly, so you keep rolling and the wall still reads uneven to the camera.
The key is noisy and full of spill
A green that's “close” sits off-target for the keyer, so edges are noisy and green spills onto talent.
Hot spots wherever the light hits
Any sheen bounces glare back at the lens and breaks up an even wall.
Touch-ups don't match the wall
Re-mixed or different-batch paint keys differently, so patches show and you end up repainting.
Why this range
Why Chroma Key over a generic green
A quick spec snapshot. The short version: it's engineered for the camera and built to stay consistent for the life of the wall.

Step 2 · Choose your colour
Green or blue?
Key on the colour that appears least in your foreground — wardrobe, props and set. Pick one and we'll focus on that exact paint: specs, coverage and how to buy.
Chroma Key Green (5711)
The default for most studios — brightest key, least light needed.
Chroma Key Blue (5710)
When the foreground has green in it, or you want lower spill on skin.
