has anyone come across the difference in rendering colors between apple and the rest of the world yet? i have a pdf document generated from quark where the colors are being changed radically (as in they are going from orange to green). column preview and preview.app are.. wrong. acrobat 7, ghostview 4.1, and photoshop 7 are all showing it correctly (or, at least, the color i was expecting).

any help, tips, pointers, or places to look for answers would be most appreciated.

You don't understand color on computers do you?

Preview is probably showing the proper colors based on the embedded ICC profile, and the rest ignore that by default. I know that you have to turn things on in Photoshop, Quark usually has no clue (but you can turn it on... it is a bit quiry/quarky), I don't know about Acrobat, and Ghostscript is unlikely to be color-savvy.

And the difference between Apple and the rest of the world comes down to two thing: a different gamut than Windows by default, and actual color controls. In the 90's there were a bunch of companies that came out with really expensive packages to make color correction work on WindowsNT... They have all gone away now, and Apple just keeps working with ColorSync.

Photoshop sees ICC profiles by default, doesn't it?

Sees, but does nothing with (I think). You have to turn on color corrections. Same for all of the Creative Suite.
