Common questions
FAQ
Chroma key replaces a specific colour — usually green — with a chosen background in video software. Film the subject against solid green; software detects all matching green pixels and substitutes the new background. Green is preferred as it's farthest from human skin tones.
Yes. Display this green screen fullscreen on a monitor behind you, then enable Zoom's or Teams' "physical green screen" option. This gives better edge detection than software-only virtual backgrounds.
The standard is approximately #00b140. Our tool defaults to this shade, with a slider for fine-tuning. For OBS, Premiere, or DaVinci Resolve, sample the exact hex value from your screen.
Digital camera sensors (Bayer filter) capture twice as many green pixels as red or blue, giving the clearest separation. Green is also most distant from human skin tone across all ethnicities.

How chroma key compositing works
Chroma key is a visual effects technique that replaces a solid colour background with a different image or video. You film or photograph a subject against a uniform green screen, then video software identifies and removes all pixels matching that green, replacing them with a virtual background. The technique is used in everything from Hollywood blockbusters to weather forecasts and YouTube videos.
Why green and not blue or red?
Blue was the original chroma-key colour in film production. The shift to green happened with digital video because modern camera sensors (using a Bayer colour filter array) capture twice as many green pixels as red or blue — meaning green has the highest resolution and easiest-to-clean edges. Green is also the colour most unlike human skin tone across all ethnicities.
Our Blue Screen is available if your subject's costume or props include green elements that would be accidentally removed.
Using a monitor as a green screen
A high-quality monitor displaying this green screen tool makes an excellent improvised chroma-key backdrop for product photos, portrait shots, or video calls. For best results: keep the screen as bright as possible, avoid placing the subject close to the screen (to prevent green spill), and ensure consistent room lighting.
