The fastest way to reach us is email. It's read by Mark Thurman — not a ticketing bot — and we try to reply within a few working days.
Good things to email about
- A verdict looks wrong. Send the two colours (hex is perfect) and what you expected. Contrast maths are exact, so if something's off we want to know immediately.
- A bug. Tell us your browser and, if you can, the steps to reproduce it.
- A feature. Colour-blindness simulation, palette export and a browser extension are already on the wishlist — tell us what would make this genuinely useful to you.
- Accessibility. If any part of this tool is hard to use with a keyboard or screen reader, that's a priority bug, not a nice-to-have. Please report it.
