I recently purchased a ColorVision Spyder 2 to calibrate my MacBook Pro display (I have the 9C83 panel). The results were wonderful—everything seemed to improve colorwise. There is one exception, though: in applications that use ColorSync (Safari, iPhoto, etc.) blues turn purple. Not just a purpleish-shade of blue—purple. The easiest way to see this is by opening a color picker, such as the one in Pages or Adium. Using the RGB sliders to choose a perfect blue—255—it's easy to see that it's purple. Other interface elements changed, too: blue menus, such as when you organize bookmarks in Safari, become purple. I found a long thread about the issue here, but no conclusion seems to be reached. It looks like the color spectrum created by these hardware profilers puts blue very far away from the sRGB blue, causing an adjustment to purple. A lot of people here use calibration tools on their MacBook Pros—has anyone else seen this? And you if have, is there a workaround?
