About ColorScreen.dev

ColorScreen.dev is a free, browser-based collection of screen color tools — white screens, blank screens, pixel tests, lighting aids, and fun effects. Everything runs directly in your browser. No app to download, no account to create, no personal data collected.

What it does

Open any tool, press fullscreen, and your display fills with a solid color, animated effect, or interactive screen. Common uses include:

• Finding dead or stuck pixels on monitors, laptops, and phones
• Using your screen as a photography fill light or makeup light
• Cleaning your monitor by revealing smudges on a solid background
• Blanking secondary displays for focus and distraction-free work
• Calibrating monitor color accuracy and backlight uniformity
• Pranking coworkers with fake BSODs, broken screens, and fake updates
• Running retro screensavers like the DVD bounce or flip clock
• Decorative ambient lighting using colored backgrounds

How it works

Each tool is a React component rendered in the browser. Solid color screens use a single CSS background fill. Effects like Matrix, DVD bounce, and white noise are rendered on HTML canvas in real time. The Fullscreen API is used to enter and exit fullscreen mode. There is no server-side processing — everything runs locally in your browser tab.
