<p>Your browser will read a profile embedded in the picture then "interpret" it to match it the colour profile of your monitor to give you a visible image as true as possible, non tagged images (most of the web) is taken as sRGB by default, other elements of a webpage will bypass the browser settings entirely (like Flash and Java), thats in theory...<br /> In practice all the browsers will behave in a slightly different way so results are not the same for all... and the problem can be in reading the embedded profile (if theres one), or in the conversion to the monitor profile, or in respecting the monitor profile for the output.<br /> IE now is color managed (since IE9) but rather badly since it seems to not care about the color profile of the monitor when it sends to it, it will read the embedded profile correctly and... then assume your monitor color space is sRGB and convert to that :(<br /> Other browsers do a much better work of it but some will let you tweak their settings better than others: Chrome isnt that great in the way it manages some monitors color profile and doesnt support all of them either... Firefox seems to handle things better than the rest giving better color management right as it is, and more possibility (and ease) to tweak things if necessary.<br /> Essentially it comes down to the performance of the whole thing, while in the past the system was ok now with changes of hardware we use it needs to be improved. I think performance is also the reason IE does the work half way and then output everything in sRGB...<br /> The way i see it is that, as it is now, you pick the colours of your walls from the manufacturer swatches, every home depot employee will interpret the formula to get to that color in its own way, so that at the end the paint in the can you buy will never be always the same and at the end every wall will dry the paint to a slightly different tonality...<br /> PS: OS can be a problem too, while OS like Windows now says its "colour aware" in reality there are mixed results: some apps will manage colors others wont be able to or will not care about it. So you set your monitor profile and the pictures show properly but when you browse folders you find thumbnails with the wrong colors (but the corresponding picture displays correctly because the viewer manages the color), desktops arent displayed properly, spreadsheets are impossible to look at etc... ask MS and they tell you its the video card... mah...</p>
<p>Edit: Now that you did that on chrome it will browse assuming all page contents are sRGB. You might have to change also for the other ways to launch Chrome (in case you would check for image changes and not see difference clear the cache)</p>
