How many colour screens are there?
Twenty-four named colours have their own pages, and any other shade works by putting its hex code in the address.
The named pages exist because people search for them by name — "red screen", "black screen", "pink screen". Everything else is reachable at /screen/ followed by six hex characters, which covers the remaining sixteen million.
Which colour screen should you use?
White for light and for spotting dark specks, black for OLED and stuck pixels, mid grey for uniformity, and warm colours for flattering light.
The white screen is the general-purpose one: maximum output, neutral cast. Use the black screen on an OLED, where black pixels switch off entirely, and to find pixels stuck bright. The grey screen is the reference field for uniformity faults. For lighting a face, the pink and coral screens are kinder than plain white.
Can you download these colours as images?
Yes. Every colour page generates a PNG, JPG or WEBP at any size from a single pixel up to 8K, with no watermark.
PNG files are built on the server as one-bit palette images, so an 8K download is a few kilobytes rather than a few megabytes. The white screen 1×1 page lists every size with its measured file size and explains which format to pick.
Do colour screens work on a phone or a TV?
Yes, on any device with a browser. Add the page to a home screen on mobile, or open the link in a TV browser.
Because the colour travels in the URL, the same link opens the identical shade on every device — which is the reliable way to agree on a colour without screenshots.
