What is a smoke screen?
A smoke screen is simply a web page filled edge to edge with one solid color — Smoke, hex #738276, or rgb(115, 130, 118). It is a mid-toned, neutral color: in HSL it sits at 132° hue, 6% saturation and 48% lightness, and its relative luminance is 20.9%. The closest standard CSS color is Gray (#808080).
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 smoke screen for
Black screens save power on OLED and AMOLED displays (each black pixel is switched off), reveal backlight bleed and IPS glow on LCDs, and cut glare and eye strain at night. A true-black field is also the go-to background for photography, cinema-style letterboxing, and hiding a screen that has to stay on. Mid-gray fields are the neutral reference for panel-uniformity and colour work.
Beyond that, a smoke screen is handy for all the things any solid-color screen is good for:
- Checking a display for dead or stuck pixels — a flat smoke field makes a bad pixel jump out.
- 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 smoke 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.
