If I look at the picture here in Safari, Preview or the finder, the shades of blue are significantly different than if I look at the picture in Google Chrome (they are less saturated than in Chrome).

Since I am a photographer and need to prepare pictures for publication online, I need to know what a jpeg should really look like, in order to color-correct it.

I have an excellent Eizo monitor that is correctly calibrated.

If I open the same image in Photoshop CS3, I get the Chrome colors if I use Monitor RGB under view >> proof setup, and I get the Safari colors if I use Macintosh RGB.

Can anyone explain the difference between these two settings, and the difference between Safari and Chrome? Which colors are correct?

Photos that I prepared under Windows (during the past five years) now seem washed out in the Apple Finder and Preview, even though I had correctly prepared them.

Is there a setting on the Macintosh for color calibration, besides the monitor calibration control panel?
