AppCenter brand colors don't pass the contrast check

danirabbit opened this issue · comments

Describe the bug

The chosen brand colors in your appdata.xml don't pass the contrast check. This means it could be hard for folks to read if they have a vision disability or a display with poor contrast reproduction.

Currently the chosen colors achieve a contrast rating of 2.5:1 which is below WCAG A level

Expected behavior

We usually advise striving for WCAG AA level contrast which is 4.5:1 or higher

Screenshots

This is your current, less than A level contrast:

With a minor adjustment you could achieve A level:

By taking the text color all the way to white you could get to AA. To go even higher, the background could be slightly darker or more saturated:
