Pure color screen
Green Screen
Open a green screen (#00FF00) for chroma-key setup and green-channel checks. Use it fullscreen or download free 1080p and 4K PNG backgrounds.
This is an exact solid green field for chroma-key preparation and green-channel inspection, not video editing software.
How to use this green screen
Open the solid field fullscreen to frame a small chroma-key shot, inspect a green background, or check how your display renders its green channel. Use the PNG downloads when you need the same pixel value as a static backdrop in an editor or presentation.
Chroma-key setup
Use the fullscreen field as a quick background for small objects, video-call framing, or a keyer preview. Keep the subject separated from the display and check the camera view for green spill before recording.
Green-channel inspection
A pure green field isolates the display's green channel, making dark, weak, or off-color areas easier to notice. Use the dedicated LCD Screen Tester for a guided multi-pattern diagnosis.
Even coverage matters
A usable key depends on consistent color and exposure across the frame, not maximum brightness. Check for screen reflections, hotspots, and edge falloff, then adjust the display and camera for a flatter background.
Technical note
This page renders the exact CSS color #00FF00, or rgb(0, 255, 0), with red and blue set to zero. Production keying may use a different green, and even lighting, exposure, camera white balance, display settings, and ambient light all affect the recorded result.
For deeper pixel diagnosis, use the LCD Screen Tester. To inspect actual dimensions, use the Screen Resolution Checker.
Frequently asked questions
Is #00FF00 the standard production chroma-key green?
Not always. #00FF00 is exact CSS green, while studios may use a different fabric, paint, or digital key color chosen for their camera and software.
Can this page remove a video background?
No. It supplies a solid green field or PNG; background removal still happens in your camera, streaming app, or video editor.
Why does the green look different through my camera?
Camera exposure, white balance, picture profiles, display brightness, and room light can change the recorded color. The page's pixel value remains #00FF00.
