Reporting a wrong result

Please include the page address, the exact color or number you entered, what HexaCalc showed and what you expected. A screenshot helps. For color pickers, mention your browser and device, since screens and camera processing differ.

Accessibility problems

We aim for WCAG 2.2 AA across the site. If something cannot be reached with a keyboard, is unreadable with a screen reader or has poor contrast, write to us with the subject line “Accessibility” and we will treat it as a bug.

Feature ideas

Tell us which job you were trying to get done and where the current tools fell short. Requests that come up repeatedly go to the top of the list.

Advertising and partnerships

We do not sell links or publish sponsored reviews. Product partnerships, if we ever take any, will be labeled and marked rel="sponsored".

We read every message but cannot promise a reply to all of them. We never sell or share your email address.
