- Thread-topic: testing color browsers for ICC compatibility
I am not surprised by Marco's findings re profile awareness in browsers but
I was surprised by his comments re the default to the monitor profile. I
have some 'toned greyscale' images which look fine in Internet Explorer,
Netscape and Opera - three browsers which fail the test below. (A toned
greyscale image is a great check because even relatively subtle shifts in
colour interpretation are obvious.) The images are tagged sRGB and since
the colour is right I assume these browsers default to an assumption that
all images are sRGB. (Incidentally, because Adobe Bridge is not working
properly at the moment I have a colour check for something which displays
using my monitor profile (we believe) and not the embedded or assumed sRGB.)
While many browsers are not colour profile aware, it's not that alarming if
we can make assumptions with reasonable confidence that they at least
interpret colour according to a constant benchmark, sRGB. If that benchmark
shifts according to the viewer then it really is alarming. I really do
suspect though that the latter is not the case. I have consistent colour
interpretation across the Safari, Opera, Internet Explorer and Netscape
(Mac) for any sRGB images. As a result, at least the situation is
predictable - convert to sRGB and you're fine.
