How to Use
Chroma Key Setup Guide
This screen uses #00FF00 (pure chroma green), the standard color recognized by all major video software. Position a secondary monitor or tablet behind or beside you, then apply the chroma key filter in your software.
• OBS Studio: Add source → Video Capture → Filters → Chroma Key
• Zoom: Settings → Background & Effects → Virtual Background
• Teams: Background effects → Custom background upload
• Streamlabs: Scene → Add Source → Chroma Key filter
Tips for Best Keying Results
- • Use a tablet or second monitor showing this page as a portable chroma key backdrop
- • Ensure even lighting on the green display — shadows and reflections reduce keying quality
- • Avoid wearing green or teal clothing when using this as a background
- • Set screen brightness to 100% for maximum color saturation
- • The larger the screen behind you, the more natural the virtual background appears
- • For best results, sit at least 60cm away from the green screen display
Green Screen vs Blue Screen for Chroma Key
Both green and blue are used as chroma key colors, but each has specific advantages depending on the shooting scenario:
Use Green Screen when:
- • Subject is not wearing green clothing
- • Shooting indoors with controlled lighting
- • Using digital cameras (better green channel sensitivity)
- • You want the most compatible option (most software defaults to green)
Use Blue Screen when:
- • Subject is wearing green or yellow clothing
- • Shooting outdoors near greenery or grass
- • Working on traditional film production
- • Subject has blonde or light-colored hair that spills green
Frequently Asked Questions
Can I use a monitor as a green screen background?▼
Yes. A monitor, laptop screen, or tablet displaying this pure green screen can be used as a chroma key background in OBS, Zoom, or any streaming software. Place the screen behind you and apply the chroma key filter in your software. Larger screens produce better results as they cover more of the background in the camera frame.
What hex code is chroma key green?▼
The standard chroma key green used in digital video is #00FF00 (pure green / lime green). This is R:0, G:255, B:0 in RGB format. This screen uses exactly that value. Some productions use a slightly different "studio green" shade, but #00FF00 works with all major keying software.
Why does green screen not work in bright sunlight?▼
Direct sunlight creates very uneven lighting on the green screen — bright spots and dark shadows — making it nearly impossible for the chroma key algorithm to cleanly separate foreground from background. For best results, use diffused, even lighting from multiple soft light sources, or simply use the screen in a well-lit indoor setting.
What pixel failures can the green screen reveal?▼
On a pure green screen, a stuck red sub-pixel appears as a red dot, a stuck blue sub-pixel appears as a blue or cyan dot, and a dead pixel appears as a black dot. Green stuck pixels blend into the background and are invisible — use the magenta screen to detect those instead.
