Solid Color Screen — Full-Screen Color Generator
A full-screen solid color generator: choose any color and it covers your entire screen edge-to-edge — no borders, no margins, no page breaks. Use it as photography fill light, a green-screen chroma background, bias lighting behind a TV, a dim night light, a clean color reference, or a plain white screen for cleaning and dead-pixel checks. Pick colors with a wheel, a HEX code, RGB/HSL sliders, or an eyedropper, then fine-tune brightness and color temperature.
How to Make a Full-Screen Color
Choose a preset, type a HEX or RGB value, or use the eyedropper to grab a color from anywhere on your screen.
Optionally dim the screen or set a white point — useful for bias lighting behind a monitor and for photo fill light.
Press the Fullscreen button (or the F key) to fill your entire display edge-to-edge with no browser chrome.
Copy a link that reopens the exact color, save it as a PNG image, or start an auto color cycle.

Ignore the hue and use the color temperature as a pure white point — ideal for bias lighting and photo fill.
Breathing mode slowly pulses the brightness — for relaxation and meditation. Turn it off to set brightness manually.
Gradually dims the screen to black over the set time — like a sunset lamp for falling asleep.
Blend two colors across the whole screen — linear or radial.
Auto-rotate through a sequence of colors — for mood lighting, a party backdrop, or a quick multi-color screen check.
Fast flashing can trigger seizures in people with photosensitive epilepsy. Keep the interval above 1 second or turn on Smooth fade.
Fills the screen with red, green, blue, white, black and grey in turn at full brightness. A dot that stays dark on a colour field is a dead subpixel; one that stays lit on black is stuck. Arrows step through manually.
