The only way to do it permanently and for everybody would be to reach out to the Roll20 team (<a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a>, I think) and inform them of the accessibility issue. However, in the mean time, you can create a stylish theme that would change the color. Everyone who has the issue would need to install the Stylish extension and create a them with the following code: .no-touch .ui-dialog .charsheet .repcontainer.editmode div.repitem:hover .itemcontrol{background-color:rgba(226, 185, 237,0.60)} Make the theme for the URL: <a href="https://app.roll20.net/editor/" rel="nofollow">https://app.roll20.net/editor/</a> To modify the color to your liking, just change the first numbers (226, 185, 237). If you need to change the opacity, modify the last number (0.60), but that will need to be a number between 0 and 1 (0 = completely transparent, and 1 = completely opaque).
