I've recently added a second display (NEC P221w) and I've been working to calibrate and profile the new display to match my primary display (Eizo CE210w). After some struggles I think I have the displays set up pretty well but noticed that I'm still seeing oversaturated reds on my website on both displays. As it turns out, what I mistook for higher contrast on this blog was actually a color management issue in the browser.
Most of you will not be affected by this issue because it requires a particular combination of software and hardware:
a color-managed browser (Safari, Firefox)
a wide-gamut display (both of the above are)
Mac OS X ? (I'm not clear at this point about Firefox on Windows)
The bottom line is that color-managed browsers make certain assumptions about the color profiles of images on the web that may not be correct, causing the color to shift in the wide gamut displays.
