About ColorScreens
ColorScreens fills a display with any color, and it is a reference for the colors themselves. Those are two jobs that usually live on two different kinds of website, and keeping them together is the whole idea.
What it does
The tool side is a utility. Fill a screen edge to edge to clean it, to hunt a dead pixel, to check a panel for backlight bleed, or to turn a phone into a soft light for a video call. It runs in a browser, needs no install, and asks the browser to keep the display awake while a color is showing.
The reference side covers 111 named colors. Each one carries its hex, RGB, HSL, HSV, CMYK, HWB, Lab, LCH, Luv and XYZ values, shade, tint and tone ramps, six harmony schemes, four palettes, and WCAG contrast grades against black and white. There is also a palette generator and a contrast checker.
Where the numbers come from
Color values are labelled by where they come from, because the difference matters to anyone about to paste one into real work.
- A color marked CSS keyword takes its hex from the CSS Color Module. That value is normative. A browser renders the color from the name alone and the value cannot vary between sources.
- A color marked common convention has no standards body behind it. The hex shown is the value in widest use, and other sources will differ slightly. Saying so is more useful than implying a precision that does not exist.
- Everything derived from a color, including every space conversion, contrast ratio, ramp and harmony, is computed from the hex using sRGB with a D65 white point. Nothing is transcribed by hand, so nothing can be mistyped.
Why it is free
Every feature on this site is available to everyone. Nothing is held back for a paid tier, and there is no account to create. The site is designed to be supported by advertising, which is a trade worth stating plainly: you see ads, and in exchange nothing is locked.
Ads are not running yet. When they are, they will sit in reserved space on the page and never inside the fullscreen view, because interrupting the one thing the tool exists to do would be self-defeating.
Who makes it
ColorScreens is built and maintained by Kinsey Street Online Marketing, a small independent publisher. It is not backed by a design tool company and does not sell anything of its own.
