Rosco Chroma Key and Ultimatte Paint

Pure Enough for Clean, Crisp Key Effects

Getting a good, clean matte is an essential part of modern production workflows. Sure, you could save a couple of bucks by buying a knockoff that happens to be the same hue as Rosco Ultimatte or Chroma Key paint, but you'll probably regret it when you see what a crummy mask it gives you.

Do you need tape, cable, fabric or flooring for keying? Check out the Rosco DigiComp line!

That's because only Rosco matte paints are the right combination of hue, luminosity, and uniformity to give you reliable, clean mattes every time.

Values measured with an Ikegami EC-35 camera with Plumbicon tubes. The iris was set so that an 89.9% reflective chip on a Porta Pattern 11 step chip chart was at 100 IRE units, the gamma was set to 0.45, and the knee circuit was turned off. Different cameras may yield different levels, even under the same conditions.
