Chroma Key Blue — the clean key when green won't do
Blue is the answer when your foreground fights a green key — foliage, hi-vis, greenery or green wardrobe — and it spills less on skin tones for a more natural edge. Chroma Key Blue (5710) brings the same purpose-made, ultra-matte, two-coat performance in a blue key.
Is blue your key?
When blue is the right key
Blue earns its place in specific but common situations.
Green in the foreground
Foliage, hi-vis, greenery or green wardrobe would conflict with a green key.
Skin-tone work
Blue spills less on skin for a more natural edge on people.
Night & certain looks
Matching a night exterior or a look that simply suits a blue key.
Problems it solves
The blue-screen problems it solves
Same purpose-built engineering, tuned to a blue key.
Green key fought the subject
Green in shot makes a green key impossible.
Heavy spill on skin
Green spill is hard to remove from faces and hands.
Patchy, glossy DIY blue
Cheap blues need coats and still shine.
Touch-ups drift
Batch variation shows on the wall.

Application
Lay it down right
Blue keys reward even lighting. Prime, two coats, and light it flat and clean.
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.
