ScreenWhite

ScreenWhite is a full-screen colour tool for anyone who needs a blank, lit surface. Press Full screen and your display fills with pure white — useful as fill light on a video call, as a light table for tracing, for spotting dust when cleaning a monitor, and for finding dead pixels.

Beyond white there are 23 named colours and a page for every hex code, so any shade has a shareable link. A brightness slider and a colour temperature control tune the light to the room, and a wake lock keeps the display from sleeping — something most white screen sites miss. Any colour downloads as a PNG, JPG or WEBP from a single pixel up to 8K, with no watermark and nothing stored on a server.

The site also includes screensavers, display tests and a handful of prank screens. No ads, no sign-up, no account.
