Google Chrome has been colour space aware since version 3 (I think) but a recent search for "Google Chrome colour management" on Google, ironically, did not yield instructions for how to activate it. For this reason, and for personal reference, I am posting the instructions here. I have only tested this functionality in Windows Vista but I am guessing that Windows XP w/ Windows Color Control Panel installed and Vista and beyond plus Mac OS should work similarly.
In your shortcut to launch Google Chrome you'll need to add this switch after whatever you find in the "Target" box in the shortcut's properties:
So it should look something like:
Now just make sure that you use the shortcut and not some other way to launch Chrome and you should be set. Hopefully Google will integrate colour management settings into a control panel similarly to how it is handled in Firefox.
Colour management doesn't appear to be perfect in Chrome... or rather, colours are better than non-colour-managed Chrome but different than other colour-managed applications. Remind me to look back into this, hahah.
Which other colour-managed programs are you using for your comparisons?
It may also be worth noting that newer versions of Firefox have colour management enabled by default and there are now two non-non-colour-managed (yup, two "non's") colour handling modes. One of these modes will translate even non-tagged images to the destination colour space and the other method will translate only tagged images to the destination colour space but leave the untagged images untranslated which I means it will just assume that untagged photos are in the colour space of the monitor. If you are comparing to colour reproduction of Chrome to that of Firefox and you are using a combination of tagged and untagged images my guess is that that may be one of the sources of differences.
The page that you linked appeared to have been last updated with notes on Google Chrome almost two years ago when Chrome was still in beta. Did you try the method explained in this blog entry? If your operating system's colour management is properly configured, you should see that the browser is colour space aware. That said, some people have reported Chrome interpreting colour differently than Firefox and Photoshop even when the -enable-monitor-profile switch is used.
As of Nov-08-11, Chrome still does not support color-managed with pictures embedded with Adobe profile. I compared both my pictures in Firefox and Chrome version 15.0.874.106 m, the Firefox displays my pictures exactly same as I see in CS5. Don't know if there is another hidden option somewhere that I can turn on. I like Chrome because it is faster than Firefox, but speed alone is not good enough if I can't have the color-managed feature working.
