How to use a pure green full screen for chroma key and display testing
Yes. Show the green screen on a monitor, tablet or phone behind a small object or inside the shot, then remove the green in editing software such as Premiere Pro, DaVinci Resolve, CapCut or OBS. It is ideal for small product shots and for replacing what is shown on a device screen in your video.
Bright green is far from human skin tones and hair colors, so it can be removed cleanly without cutting into the subject. Most camera sensors also have twice as many green pixels as red or blue, which gives cleaner detail in the green channel and a smoother key.
Open this page on the device you are filming and go full screen so the display shows solid green. Record your shot, then key out the green in your editor and place your app demo, video or image on the screen. Lower the device brightness a little to reduce glare and green spill.
A pure green (#00FF00) screen lights only the green sub-pixels. Scan the display in full screen: a black dot is a dead green sub-pixel, and a red, blue or white dot is a stuck sub-pixel. Use the red and blue screens to complete the test.
Pure #00FF00 is a good start for screen-based keying. If the green reflects onto your subject, try a slightly darker green with the RGB or HSL controls. Avoid green clothing and props, since they will be keyed out too.
