About Blue Screen

Blue chroma keying is the older Hollywood-style key. Color #0067FF avoids the green spill you sometimes get on talent wearing green clothing, and it tracks well in dim environments. Same fundamental usage as green: fill a second display, light the screen evenly, and key it in software.

Blue Chroma Key for Hollywood-Style Keying

Blue screen keying predates green screen in film production and remains the preferred choice when subjects wear green clothing, work in green environments, or have green props in frame. The #0067FF blue fill avoids green spill — the green tint that contaminates skin tones and edges when keying against green. Hollywood VFX departments established blue screen as the standard for outdoor shoots and scenes with foliage. Use this tool on a second monitor positioned behind your subject, light it evenly, and configure your keying software to sample the blue channel. The result is cleaner edge separation than green screen in many real-world scenarios.

Set Decoration and Ambient Blue Lighting

A blue fullscreen page transforms any monitor into an ambient blue light source for set dressing, mood lighting, and creative photography. Filmmakers use blue wash lighting to create night-scene atmosphere, and a monitor displaying pure blue achieves a similar effect without renting dedicated lighting fixtures. Event organizers use blue screens on lobby displays and stage monitors to create a cool, professional ambiance. Photographers use the blue fill as a color gel substitute — place it off-camera to add a blue accent to portraits, product shots, and still-life compositions.

Gaming and Streaming Blue Accent

Gamers and streamers use blue screen monitors as ambient accent lighting behind their desk setup. The blue glow creates the signature gaming aesthetic associated with competitive FPS and sci-fi titles. Streamers incorporate blue background elements into their set design for a cool-toned visual that complements RGB keyboard and peripheral lighting. The brightness slider lets you match the blue intensity to your existing RGB ecosystem, from a subtle accent glow to a dominant room color.

How to use it

  1. 01

    Open and fullscreen

    Press F. The panel fills with #0067FF.

  2. 02

    Tune brightness and color temperature

    Open the controls panel (gear icon or press C). The Brightness slider dims the surface from 20% to 100% — useful for night work or for matching ambient room light. Keyboard + and − nudge it 5% at a time. The Temperature slider warms the screen toward amber (positive values) or cools it toward blue (negative), letting you bias a fixed hue without leaving the page.

    Download the current view as a PNG

    Click the download icon in the top-right toolbar — it sits between the settings gear and the fullscreen button. We detect your display's physical pixel count (screen resolution × device pixel ratio) and rasterize the current configuration into a Retina-sharp PNG. The file lands in your browser's default downloads folder; to save straight to the Desktop, enable 'Ask where to save each file' in your browser settings. The filename includes the resolution so you can keep multiple variants side by side.

Frequently asked

The shortest path between you and the answer.

Is this tool free?

Yes. Every ScreenTools.co tool is free, with no account, no paywall, and no install.

Does it work on mobile?

Yes. Layouts adapt to phone and tablet screens. Mobile Safari restricts true fullscreen, but the page fills the viewport and you can add the page to your Home Screen for an app-like experience.

Does it work offline?

Once a tool's page has loaded once, the runtime is local. A few tools that fetch fonts or icons need the first hit online; after that, refresh works offline.

Does this collect my data?

No personal data leaves your browser. The site has lightweight, privacy-respecting analytics for aggregate counts (which tool was opened) and nothing else.
