A fullscreen chroma-key backdrop for basic keying in video calls, streaming, and casual video production. Uses the industry-standard chroma green (#00B140) by default, with blue and magenta alternatives for when your subject is wearing green or standing near foliage. Free to use, no sign-up, and it works instantly in any modern browser.

How to use it

  1. Position the screen behind your subject, with even lighting on the backdrop and no glare or shadows crossing it.
  2. Go fullscreen so no browser chrome interrupts the color.
  3. In your keying software (OBS, Premiere, Final Cut, DaVinci Resolve, or your video call app's background effect), select the chroma key color by sampling directly from the screen rather than assuming a preset.
  4. Switch to blue or magenta if your subject's clothing or surroundings share too much green.

Frequently asked questions

Will a monitor really work as a chroma-key green screen?
Reasonably well for casual use. It won't match a dedicated fabric or paper backdrop in evenness across a large area, since a screen is smaller and glossier, but for a webcam-distance shot it keys out cleanly in most video software. For a full-body or large-set shoot, a physical backdrop still works better.
Why would I use blue or magenta instead of green?
Green is the default because it's rarely present in skin tones or clothing, but it becomes a problem if your subject is wearing green or sitting near a lot of foliage. In that case, blue is the standard alternative. Magenta is useful when both green and blue appear somewhere in the shot.
What settings should I check in my keying software?
Most software (OBS, Premiere, Final Cut, DaVinci Resolve) has a color picker for the key color. Sample directly from the screen rather than assuming a preset green. Even, diffused lighting on the backdrop with no glare matters more than the exact shade.

Cedrick Reese built this backdrop tool. The green is #00B140, a widely used chroma green reference, with chroma blue (#0047AB) and magenta (#FF00FF) as alternatives; the color reference is cited in our chroma key guide. All three are fixed values in the page's code. The keying itself happens in your video software, so results depend on its settings and your lighting, not on this page.
