About Us

What this site is.

A Green Screen is a single-purpose browser utility. Open a page, press one button, and your entire display becomes a flat field of one colour. The green screen is the main tool, rendering pure #00FF00 for chroma key work. Around it sit blue, yellow, orange, pink, and purple screens, a green screen image generator, and Zoom Lighting for adjustable warm-to-cool webcam light.

That is the whole site. There is no dashboard, no upsell, and no second version behind a login.

Why a web page instead of an image.

The obvious alternative is to search for a green image and open it. In practice that gives you a file at the wrong aspect ratio, letterboxed with grey bars in an image viewer, compressed enough to have a soft halo at the edges, and often not quite the colour a keyer expects.

A browser paints the colour directly, at your display's native resolution, with every pixel mathematically identical. Fullscreen removes the interface so nothing but the colour remains. For keying, lighting, and panel inspection — the three things people actually want a solid colour for — that difference matters.

What the tools do.

Every screen page shares the same set of controls: one-click fullscreen, a brightness slider that dims the colour without shifting its hue, an option to hide the cursor so it is not sitting as a dark speck in your light, a 10-hour session that holds a wake lock so a long shoot never dims mid-take, and a download that generates a flat image in HD, 4K, mobile, or square as PNG, JPG, or WebP.

The colour pages also publish their exact hex and RGB values with a copy button, because if you are matching a colour in a design tool you need the number, not an eyedropper guess.

What it is not.

These are practical tools, not measurement instruments. Every panel renders colour differently — OLED and LCD disagree markedly on saturated tones, and colour profiles, HDR handling, brightness, and night-shift modes all shift the result further. Two devices showing the same page will not look identical, and neither is wrong.

So: use a solid colour field as a first look at a display, not a diagnosis. Use the green screen for casual keying and small subjects, not as a substitute for a lit backdrop on a full-body shot. Use Zoom Lighting to look better on a call, not for colour-critical production. Each page says plainly where its limits are rather than pretending it has none.

Privacy, by construction.

Everything happens on your device. The colour is CSS, the brightness is a slider, and downloads are drawn on an HTML canvas in your own browser — no image is ever uploaded, because none is ever sent anywhere. There is no account, no camera or microphone access, and no upload path in the site at all. Your light or dark theme choice is kept in local storage on your device and nowhere else.

This is not a policy so much as an architecture: the site has nothing to collect because the tools never need it. The Privacy Policy covers hosting, email, and external links in full.

If a page misbehaves, a control is unreachable by keyboard, or there is a colour or preset worth adding, we would like to know. The Contact page explains what details make a report easy to act on.
