Paul,
Last time I tried it, ME performed OK with sRGB, not going green.
Check your browsers with http://www.color.org/version4ready.html
Some browsers color manage correctly. Some have horrible bugs, worse
than just ignoring the profiles.
Increasingly I find that images on the web are tagged. My guestimate
is about 10% of those posted in 2005 and 2006. For example
http://imdb.com/title/tt0367959/
Many images posted after late 2004 are tagged because Photoshop CS
embeds profiles by default. Sometimes you can even tell the date when
a company upgraded their tools.
These images are most often tagged with sRGB IEC61966-2.1 or Adobe RGB (1998).
Interestingly, Google, Amazon and other big sites strip the profiles
100%. Washington Post doesn't.

I know this question has been raised a few times even by myself before,
but having not found a satisfactory solution so far, here is another try!
Being myself a Mac user and using browsers other than M.E. , which is
dead as far as Mac is concerned, I am regularly confronted to color
consistency problems. The point is that most users use M.E. on PC.
M.E. has a nice feature, it is that it can use ColorSync. But it has
also a flaw that ruins the prospect of using this capability for color
consistency: it considers untagged images as sRGB. So untagged images
that look right on all platforms, turn green when ColorSync is activated
in M.E.
I am keeping out of considerations such as "average PC screens display
sRGB colors", since more and more screens are now calibrated, and also
it would be a shame to have to display images that do not look right for
all Mac aficionados, and for PC users who have made the effort of
calibrating their display, in order to have them approximately right on
the mass displays of people who do not really care.
So my question to web developers would be: How to circumvent the fact
that M.E. reads untagged images as sRGB? Would there be a script of some
sort that would tell M.I. not to assign sRGB to untagged images? Or is
there any other trick that would help?
Thanks!
Regards,
Paul Schilliger
