Email is the whole system
Contact Us
Bug reports, accessibility problems, feature requests, or a question about a tool — send an email. There is no form, no ticket queue, and no account required.
Tell us what you were doing, what you expected, and what happened instead — plus your device and browser. That is usually enough to reproduce anything.
Try these first.
Fullscreen will not start. Fullscreen must be triggered by a real click or tap, so it will not fire from a bookmarklet or an automated action. Check that your browser is not blocking fullscreen for the site, and note that some mobile browsers substitute their own full-view presentation instead of the desktop Fullscreen API.
You cannot get out of fullscreen. Press Esc. On a phone, swipe or use the browser's back gesture. Each screen also shows an exit control when you move the pointer or tap.
The colour looks wrong. Check night mode, True Tone, HDR, a reading mode, or a custom colour profile before reporting it — any of those will shift a saturated colour noticeably. The page always sends the same pixel values; the panel decides what to do with them.
The download did nothing. The file is generated in your browser and saved directly, so a download blocker or a restrictive private-browsing mode can silently stop it. Try a normal window.
Reporting a bug.
Useful reports name the page, the device and browser (with version if you have it), and the exact sequence that caused the problem. If the issue is visual, say whether it appears on a phone, tablet, laptop, or external monitor — behaviour genuinely differs across those.
Screenshots help for interface problems. They rarely help for display problems: a camera pointed at a screen adds moiré, colour shifts, and exposure artefacts of its own. For a suspected pixel or uniformity fault, describe where it is and whether it survives switching to other colours.
Accessibility.
Accessibility reports get priority. Tell us if a control cannot be reached or operated by keyboard, if focus disappears, if a button has no clear name in a screen reader, if text breaks when enlarged, or if an instruction depends on seeing colour. The description of the barrier is the important part — mention your assistive technology only if you are comfortable doing so.
One caution that applies to everyone: these pages display large, bright, saturated fields. Keep your device brightness comfortable, and stop if the light causes discomfort, headache, or eye strain.
Feature requests.
Worth asking for: a colour that is missing, a download size that would be useful, a preset for Zoom Lighting, a keyboard shortcut. When you ask, describe what you are trying to accomplish rather than only the feature — the underlying task often points at a better solution than the one either of us thought of first.
What we do with your message.
Messages are read and used to answer you and fix what you reported. We may ask a follow-up question if something is hard to reproduce. Please do not send passwords, payment details, or personal documents — nothing about a browser colour tool requires them, and we do not want them. The Privacy Policy covers how email is handled.
Contacting us is entirely optional. Every tool on the site works without it: the green screen, the green screen download, the colour screens, and Zoom Lighting are all free and need no account.
