What is a alice blue screen?
A alice blue screen is simply a web page filled edge to edge with one solid color — Alice Blue, hex #F0F8FF, or rgb(240, 248, 255). It is a very light, cool color: in HSL it sits at 208° hue, 100% saturation and 97% lightness, and its relative luminance is 92.9%. alice-blue is one of the standard CSS color names, so it renders identically in every browser.
Turning a display into a single flat color is more useful than it sounds — as a light source, a test pattern, a video or photo backdrop, or ambient lighting. This page is that color, ready to open full screen or download, with no app to install and nothing uploaded anywhere.
What people use a alice blue screen for
White screens are the most-used solid colour of all: a full white field is a light source. People use one to check a monitor, phone or TV for dead pixels, dust and backlight bleed, as a tracing light-pad, as a fill light for video calls and photography, as an improvised flashlight, and as a clean background for scanning or product shots.
Beyond that, a alice blue screen is handy for all the things any solid-color screen is good for:
- Checking a display for dead or stuck pixels — a flat alice blue field makes a bad pixel jump out, and it exercises the red, green and blue sub-pixels.
- Spotting dust, smudges and scratches on a monitor, phone or TV before cleaning it.
- Bias or ambient lighting — running a second screen or an old phone as a soft alice blue glow behind a desk or TV.
- A clean, distraction-free background for video calls, screen recordings, live streams and product photos.
- A backdrop or placeholder for digital signage, kiosks, stage screens and mock-ups.
- Judging screen brightness, white balance and how evenly a panel lights up.
