Links to info about this... assumed colour management was only important for dealing with print, but its not. Especially with CS3 - and save for web from illustrator / psd on a mac...
This looks like a good primer from apple about colourspaces, profiles, calibration etc...

http://www.gballard.net/psd/saveforwebshift.htmldont embed ICC profiles in your save for web dialogue if you want to match graphics and coded hex colours seamlessly. see...
http://www.gballard.net/psd/save_for_web_embed_ICC_profile.htmlthat post basically has screenshots of how to have settings in save for web.
so finally this is solving why when you save for web, photos get dimmer and washed out, they actually only are on my monitor not everyones elses because my gamma is set to 1.8
but really still in 2 minds about whether to have embedded profiles when saving for web or not. i tick convert to sRGB in save for web drop down.
1/ ticking embed icc profiles makes a less washed out image when viewing in safari. for some images it actually looks too saturated, maybe because they are incorrect to begin with. note that in firefox the image wont be any different and neihier will it in vista (vista displays it sRGB regardless. so is it worth the xtra 4k.
i was just about to think yes definately, then i viewed the images on an imac and there wasnt as much difference. and actually the untagged (more washed out) image actually looked better i think because the pic is too saturated to begin with.
2/ usually you wouldnt tick embed profiles, for web type things, because in safari or colour managed browsers you will get a mismatch between a jpg and a hex coded colour background. (because the hex coded background cant possibly have an embeded profile.
3/ so i dont know what is the answer. should i embed the profile so that in mac on safari the images look more saturated and similiar to the original image or have consistency between firefox and safari and hex colours and go for the washed out version which actually looks better on some images. and saves 4k per image. and also, on my screen it looks washed out but it wont on every mac screen.
4/ but mainly the concern was that what if my screen is very similiar to other mac users, and all of them using safari are seeing non punchy desaturated colours on the web when they dont need to be. see calibrating the monitor is actually NOT normal, so if you calibrate your monitor you will see punchy colours but the users still wont so whats the point. id rather leave my monitor to be like theirs, as a reminder that this is what it is going to look like for them and remember then to make the choice of embedding profiles or not.
also this is the reason why save for web images (without embedded ICC profiles) look different in a Preview or a browser and photoshop. photoshop views them in whatever is the working colour space eg. SRGB whereas Preview's colourspace is 'monitor rgb' which is the washed out one. but if you view a tagged (icc embedded srgb profiled) image in preview, it will look the same as in photoshop.
im gravitating more now towards tagging (embedding icc profiles) in save for web images, just because it is more correct in general to have a tagged image than an untagged. The tagged image will preview correctly and consistently in the finder, preview, safari and photoshop (but look washed out in firefox or any non colour managed browser but theres nothing to do about that anyway, at least safari users are seeing something closer to correct).
And especially to embed the profile when 50% of site visitors for the type of site your working on will be creative types on a mac OSX, using safari probably. the ones that count for commercial sites (customers with money to buy the products) will have fast bandwith so no caring about extra 4k, AND if someone has supplied a SRGB image that they have been viewing in photoshop with srgb working space, then i go and untag it and they view it on safari, it will look different and washed out compared to what they gave me. this = not happy.
just workeed out why the untagged profiles look different on the imac and the laptop. laptops 'generic rgb profile' and 'colour LCD' profile is used in the finder and in preview. the imac uses 'imac' profile to view things ie its own 'generic rgb profile'
so best thing to do is in your photoshop edit > color settings, you have ticked all those boxes that say profile mismatches etc etcwhen you open and paste files and so on. its a good reminder. it also helps you know what your working with, and you can convert images destined for the web away from adobe rgb to srgb when you open. its really important to be aware of which colour space the things your using were designed in and so on and you can sort of guess what it looked like on their screen.
whatever work now.
