Note: even if this is just the result of Chrome supposedly taking into account the screen's color profile and adjusting to it, something is obviously wrong anyway:

1. I switch screens all the time. I use three different screens: two external ones (one at home, one at work), plus the laptop's built-in screen. In this span of time (a couple of weeks or so) I have seen the colors being rendered BOTH ways in each screen. When it changed the first time, I started observing the "new" colors on all three screens. When it went back to normal the first time, I started observing the "old" colors again in all three screens. When it changed again, the same. And now that it has gone back to normal again, I still have to check because I haven't switched screen since.

2. I have gone to Settings and searched for "color". Nothing shows up. If you are adjusting for color profiles, you MUST allow me to see what color profile is being applied, what you are basing the decision on (e.g. the model of the screen you detect), AND allow me to change it.

3. That the color profile being applied suddenly changes at a given random moment without switching screens, is obviously wrong.

Unable to reproduce the issue on reported chrome version #68.0.3440.106, using Ubuntu 17.10 by following below steps.

Steps:
======
1.Launched chrome.
2.Navigated to facebook.com, observed the site appeared in the normal blue color(the usually way it gets displayed).
Note: Tried with Dual monitor setup using Mac Os 10.13.3 as primary and Ubuntu 17.10 as secondary moniter, but unable to reprduce the issue.

Attached screenshots for reference.
@Reporter: Could you please review the attached screen-cast and confirm if anything being missed here and request you to retry this issue with fresh profile without any extensions/apps or reset all the flags and let us know if issue still persists.

Yeah, I wouldn't expect you to be able to reproduce it.
It's something that has happened to me randomly, with no known way to trigger it at will. Did you even read my report??

Thank you for providing more feedback. Adding the requester to the cc list.

Now the colors have changed again.

Are there any logs that I can inspect and attach??

If I go to chrome://flags and set "force color profile" to "sRGB", it fixes the issue.

So, apparently, Chrome fails to detect "the color of the window's current monitor, as specified by the operating system" correctly.
(and don't tell me it's the OS that reports the wrong profile, because Chrome is the only program affected).

That there's NOTHING in Settings about this (no mention of color profiles at all) is absolutely pathetic. Flags are cool, but being able to check and control color profiles is something a user should be able to do in Settings, at least Advanced Settings. And not just force a specific color profile or choose to use the default, but also chrome should tell me what default is being applied and where it got it from.

Unable to reproduce the issue on reported chrome version #68.0.3440.106 and latest chrome version #70.0.3534.4 using Ubuntu 17.10 by following the steps as per comment#0.

Hence removing Needs-Bisect label as it is not getting reproduced from TE end and requesting Internals>Compositing team to look into the issue.

Thanks.!
