Red Screen, Fullscreen Red Light
One click gives you a solid red fullscreen display. A red screen is more than a color test: red light is the gentlest light for dark-adapted eyes, which makes this page a night light, a darkroom lamp, and a favorite ambient backdrop for filming. Double-click for fullscreen and scroll to dim it to a soft glow.
Red Light for Night Vision
Astronomers, pilots, and photographers use red light because it barely affects dark adaptation. Reading a star chart, checking gear at night, or moving through a dark room under a dim red screen leaves your night vision intact where a white screen would reset it completely.
Red Screen as a Sleep-Friendly Night Light
Of all visible colors, red light interferes least with melatonin production. Scroll the brightness down in fullscreen, and a phone or spare monitor becomes a calm red night light for bedrooms and nurseries - no hardware needed.
Red Light Trend: Film with a Red Glow
The red screen doubles as an instant mood light for TikToks, music videos, photos, and streams. Fullscreen this page on a monitor or TV behind you and you get the saturated red-room look with zero equipment. Combine two devices - one red, one purple or blue - for a two-tone neon effect.
Red Screen Test for Stuck Pixels
A solid red field makes stuck and dead sub-pixels obvious. Look for dots that stay black, green, or blue against pure red, then cycle through our green, blue, and white screens to pin down exactly which sub-pixel is misbehaving.
Darkroom and Photography Uses
A dim red screen works as a safelight substitute for traditional darkroom work and as a red fill light for creative portraits. Photographers also use the fullscreen red field to check a camera or scanner's color response.

Frequently Asked Questions
What is a red screen used for?
Red light preserves night vision, so a fullscreen red screen works as a darkroom-safe light, a gentle night light, and a stuck-pixel test. It is also popular as a warm ambient light for filming.
Why use red light at night?
Red light has the least impact on melatonin production and dark adaptation. A dim red screen lets you read or move around at night without fully waking up your eyes.
How do I test for stuck pixels with a red screen?
Enter fullscreen and look for dots that stay a different color. Cycle through red, green, and blue screens - a pixel stuck on one sub-pixel color will stand out against the others.
Can I dim the red screen?
Yes. In fullscreen mode, scroll the mouse wheel to lower brightness to a comfortable glow.
