Color Management renders wrong colrs on a wide gammut monitor after update to 77.0.1
Hello,
After updating to 77.0.1 I've noticed that colors are way off on my Adobe rgb monitor. Colors are vivid as thought they where managed as srgb. I have gfx.color_management.mode set to 1.
Is this a bug in this new Firefox version?
Thanks, Pere

Hello pere,
All other page elements and untagged images are rendered on the full monitor color gamut, leading to inaccurate and over-saturated colors, specially on wide gamut displays. Read more about it on our browser color management guide.
In order to enable and properly configure Firefox color management, follow the steps below.
Enable it on the Firefox advanced configuration Type in about:config on your Firefox address bar.
Use the filter field to search for color_management.
Update the following fields:
gfx.color_management.mode
Set to 1 to enable color management for all rendered graphics.
The default value of 2 enables color management only for tagged images, so all page elements and untagged images are rendered in the monitor full color gamut, leading to oversaturated colors.
gfx.color_management.enablev4
Set to true to enable ICC v4 profile support.
There's no need to specify the monitor ICC profile manually as it's read automatically from the operating system.
Restart Firefox.
Test it You can check how your browser's color management is behaving by accessing our browser color management test.
I hope this will help you. Thank you.
Firefox does not implement the spec that restricts CSS colors to sRGB. Instead, it just throws the raw RGB coordinates on the screen, so e.g. rgb(100% 0% 0%) is the brightest red your screen can display. While this may seem like a superior solution, it’s incredibly inconsistent: specifying a color is approximate at best, since every screen displays it differently. By restricting CSS colors to a known color space (sRGB) we gained device independence.

Thank you for the replies!
I already had gfx.color_management.mode set to 1 and gfx.color_management.enablev4 set to true. I've checked just in case and the values are right. The problem remains...
