I have noticed that Adobe Bridge displays images with a different colour balance than Photoshop CS2. Furthermore if the files are 16bit in depth the problem is worse and there is posterisation and colour artefacts present in the Bridge thumbnnails on some images.
This appears to be a display problem with Bridge (possibly a trade off to increase speed?) I will look into the matter to see if there is a fix.
In the meantime be careful of making colour judgments of images using Bridge, check colour by opening them in Photoshop.
This behaviour has been noticed on both Windows and Mac platforms
I have come across other references to this problem in the Adobe forum but have seen no feedback from the engineering team, perhaps they are busy with Lightroom…
