@vegelund Are you per chance launching Opera by clicking the automatically created shortcut on the desktop or pinned to taskbar? That shortcut generally points to the specific Opera ver 70.0.3728.71 etc, instead of to the launcher.

Try creating a shortcut to the launcher itself, on your desktop or taskbar, and launch Opera using that. In that case the argument appended to the launcher shortcut should apply.

I have been trying to get forced sRGB back to see correct colors on my monitor.

This is the solution I’ve found on Opera 70.0.3728.71, Windows 10.

Add --force-color-profile=srgb to target line after Opera\launcher.exe
Turn off hardware acceleration.

If HWA is on, colors briefly flash correctly upon browser startup, but then revert to duller presentation.
So, for some reason HWA influences color management.

I had the same problem of colours briefly correcting and then reverting to dull. This was when I used --force-color-profile=dcip3

I then tried --force-color-profile=argb, and this has made the wide color gamut permanent.

Of course, it does not make sense why this should make a difference, but it seems to be the case.

I did not try srgb, and I am loathe to try anything else in case it breaks the current working situation, so sorry about that.

I have HW acceleration turned on.

Hi @iamkarthik, you can try to run the Opera with "--force-color-profile" switch, for example --force-color-profile=srgb.
The other accepted values can be e.g. "generic-rgb" or "color-spin-gamma24".

Hi, thanks. I've done just that. I used "argb" (which I assume is how to write adobe RBG) and the colors pop now. A bit too much actually, I didn't realise my browser colors could be so saturated (⊙_⊙;). I was on DCI-P3 previously.

Hi,

The opera://flags/#force-color-profile seems to have disappeared. The browser is now unable to use the color gamut of my monitor fully. Colors look drab compared to how they were previously.
