User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:139.0) Gecko/20100101 Firefox/139.0
Steps to reproduce:
A css background image on the body tag, set to "position: fixed" and a background color in hexadecimal code (for example #5b503b).
Actual results:
The background color is not stable or correct (too clear…).
Expected results:
The expected color should be displayed.
Thanks :)

Could you attach a test-case to the bug or a link to a page that repros the issue please? Thanks.
data:text/html,<body bgcolor="5b503b" style="position: fixed; background-image: url(https://wpt.live/images/green.png)">
Seems to render fine?
Hello,
You can see here on FFox 139.0b3 : https://kcl.dourven.com/2025/ that the background color is wrong. It should match the color of the image on the right against the background.
Thanks,
François

Thanks, can you attach a screenshot by any chance? Does it repro on a clean profile? Here that site renders the same in Firefox as in other browsers.

Does going to about:config, changing gfx.color_management.mode to 1, and then restart fix it for you? I think that we might be color-managing the image and not the CSS color.
