About A White Screen

Why a whole site for a blank screen.

The need shows up more often than it deserves to. You want to clean a monitor and cannot see the smudges. You are about to join a call and your face is in shadow. You just unboxed a display and want to know whether every pixel survived shipping. You want a plain white background behind a small object you are photographing.

Every one of those has the same answer — fill the screen with one flat colour — and for years the ways to get there were all slightly wrong. Open a blank document and you get margins and a cursor. Search for a white image and you get watermarks, off-white photographs, and files the wrong shape for your display. Install an app and you have installed an app, forever, for a thirty-second job. A White Screen exists so that the obvious answer takes one click and leaves nothing behind.

What is here.

The white screen is the main tool: pure #FFFFFF at full strength, adjustable down to a soft grey, with fullscreen, a cursor you can hide, and a ten-hour session for when the display must not sleep.

The colour screens do the same in other shades — blue for stuck red and green subpixels, yellow for stuck blue ones, pink for green, purple for banding, and orange for warm light. Each page carries its hex and RGB values so you can copy them straight into a design tool.

The white screen image page hands you a file instead of a page, in HD, 4K, phone, or square dimensions. And Zoom Lighting turns a spare display into a video-call light with a real colour-temperature scale from 1900K to 9500K.

How it works, technically.

There is no clever machinery here, and that is deliberate. The colour you see is a CSS background on an element the browser paints — it does not travel anywhere and never has. Fullscreen uses the browser's own Fullscreen API. The ten-hour session asks for a screen wake lock, a standard browser permission that keeps a display awake while a page is open.

Downloads are generated on your device: the page draws a rectangle of flat colour on an HTML canvas at the dimensions you chose and hands the result to your browser. No file is uploaded, no file is stored on a server, and no copy exists anywhere but your own downloads folder. The only thing kept between visits is your light-or-dark theme choice, in local storage, on that one device.

What we are careful about.

These are practical tools, not instruments. A browser has no idea what your panel is doing with the values it sends — brightness, colour profile, night mode, HDR settings, panel age, and the light in your room all change what you actually see. Two devices showing the same hex code will not look the same, and neither of them is wrong.

So the guidance across the site tries to stay honest about that. A colour screen can tell you where a pixel fault is, not what caused it. A screen can light a face beautifully at a metre, and not at all at three. When something needs a calibrated display, a measured light source, or a manufacturer's repair diagnosis, the pages say so rather than implying a browser tab can replace it.

Design decisions.

The most important control is the first thing you see, and the screen preview is the centre of every page. Fullscreen strips the browser away entirely when you want the display itself to be the tool. Keyboard shortcuts cover the common actions — F for fullscreen, D for download, Esc to leave.

Everything is built with standard browser controls so it stays keyboard-navigable and legible to a screen reader, works at large text sizes, and behaves on a phone as well as a monitor. Fullscreen and wake-lock support genuinely differ between platforms; where a browser will not grant proper fullscreen, the page falls back to filling the view as completely as it can.

Private because there is nothing to collect.

No account, no sign-up, no advertising scripts, no analytics of our own. This is less a policy position than a consequence of the design: a tool that paints a colour on your own screen has no reason to know anything about you. The Privacy Policy covers the details — hosting logs, email, local storage, and external links.
