(it's not worth embedding profiles unless you REALLY care about Mac users with screens set to G1.8 AND ColorSync ON in IE) it's really a matter of gamma and, thus, tonality Windows gamma has traditionally been 2.2 Mac has traditionally been 1.8 (however we are now moving towards 2.2 on both platforms, since there is no good reason to use 1.8 on Mac. Why? other than on Apple branded CRT screens G 2.2 is the nearest thing to a <native> gamma) SO: If the Mac is set to Gamma 1.8: An image which looks nice in IE Windows (let's say an sRGB image) will tend to look lighter in IE on the Mac unless colour management is switched on in IE on the Mac. If the Mac is set to Gamma 2.2: An image which looks nice in IE Windows (let's say an sRGB image) will tend to look similar in IE on the Mac whether colour management is switched on or off in IE on the Mac. You ask about saturated images, I wonder if you're thinking of trying larger workingspaces? There is no (normally found) situation when placing on the web in a different colour space, say Adobe RGB, will help. (I write <normally found> because someone somewhere with a really wierd screen will no doubt say I'm wrong). We have to generalise here. A: Since, on Windows, the image is sent straight to the screen without colour management sRGB is, effectively, used (if we accept, as Microsoft and others would like us to, that sRGB IS the generic appearance of a regular screen). If (in the above example A) we presume sRGB for an image which is actually Adobe RGB then the appearance will be desaturated. SO, to make it simple, try spread the Gamma 2.2 word among Mac users, and use sRGB on the web.
