Maroon Screen
Maroon is red at roughly half output — dark enough to be comfortable in a black room, red enough to keep most of pure red's night-vision advantage.
What people use the maroon screen for
Gentler night-vision red
Full-brightness red still dazzles. Maroon gives you the same long-wavelength benefit at a fraction of the output, which is often what you actually want in the dark.
Deep warm backdrop
Rich and low-key behind a product or portrait — reads as velvet or theatre curtain rather than as a bright colour.
Ambient warm glow
Bounce off a wall for a dim, warm room tone that will not keep anyone awake.
How to use the maroon screen
- 1Open the maroon screen — it fills the page immediately, no button needed.
- 2Press F or use the fullscreen button to go edge to edge with no browser chrome.
- 3Use the brightness slider to dial the output up as a light source or down for a dark room.
- 4Move the mouse or tap once to bring the controls back; they fade out on their own after a few seconds.
- 5Press a number key or use the colour strip to jump straight to another colour.

#800000. You can copy it from the control bar, or open the colour picker to dial in any other value and keep it in the URL so the exact shade is bookmarkable.
