Worth telling us about
- A wrong result. The most useful message we can get. Include the colour values you entered and what you expected — that turns a bug report into a test case.
- An accessibility problem. Both kinds: a contrast result you think is incorrect, and anywhere the site itself is hard to use. A colour tool that is not accessible would be a poor joke.
- A missing tool. If you came looking for something and left without it, we would rather know.
- Privacy, licensing or press. Covered by the privacy policy and terms, but ask if anything is unclear.
We read everything and reply to most things, usually within a few days. What we will not do is add you to a mailing list — there isn't one.
