What helps us fix a problem quickly
- The name of the tool and the page address, for example the color contrast checker.
- The colors involved, as HEX codes, and what you expected to get: a wrong conversion is easy to check from the input and the output.
- What you did, what happened instead, and any message you saw.
- Your browser and device, for example “Safari on iPhone” or “Chrome on Windows”.
- For a picture that would not open, its format and approximate size. Please do not send the picture itself.
Please do not send private pictures or unreleased brand colors. The tools never see them, so a few example colors that show the same problem are enough.
