Google has just released a Developer release of Chrome for Mac OS X and lo-and-behold, it still color manages. I was afraid that there was a chance that google would disable it in the final releases, so I am very happy to see this happening. Chrome manages exactly like Safari in that it doesn't manage untagged images nor CSS colors. Firefox has a mode that will color manage everything and the upcoming Firefox 3.5 will have Safari-like management turned on by default. This will cause the situation to soon be that 3 major browsers will be color managed and the dinky exception will be IE. Excellent! Now if somebody could check out if the latest developer builds for windows also color manage (use this simple page) that would be excellent. The current release on windows doesn't but it would be superb if they are changing that too.
Here is the proof: Three color managing browsers on my Mac with a wide gamut screen (screenshot converted back from my display profile to sRGB so you will see the right colors too). The colors in these images are rendered exactly the same as I found out by substracting them in Photoshop.
