This is odd, because, as I said, I don't see the purple cast in any other images. I even downloaded the file and pulled it into CS3 and the cast is still there -- so it's not just the browser. Maybe it how we are defining "cast". It's not really evident in the first image of the sky and skyscraper, but in the 2nd and 3rd it is. The second also appears over contrasty and over saturated (the oranges and reds of the streetlight and car light, and green patina of the church steeple are very, very strong. In the last image, contrast is fine, but the silver car is slightly purplish, as is the concrete, gray building stone and gutter spout on the left, and the man's blue shirt and gray trousers. To look more objectively at the colors, in PS, sampling a section of the color car's paint (a little under the "Cooper" nameplate) gives the numbers 78, 78, 104. That's not a Mini Cooper color (should be pure silver). I don't think it is me or my monitor (a Dell 2408WFP profiled with Color Eyes Display Pro and a Gretag/Macbeth Eye One device). Maybe I'm just overly sensitive to it. I always felt that my Nikon scanner produced a blue cast. And is have the color management in Firefox 3 enabled -- that's the first thing I did when I installed it. In PS, the profile is read as sRGB.

Saturation in the second image is boosted over the scan (I worked the image over in PS and CaptureNX). The boost does bring out the cast to a visible amount in the clouds.
I see what you're getting at on the third image, there is possibly still a hint of colour cast in the third image (Although that's not the scanner, Provia 400F has a very slight bias that way). I wouldn't call it visible though, unless you're extremely sensitive to it which it seems you are.
The 4870 definitely does have a cast to its scans, I have to correct each one for it, but it's a far more visible cast than anything shown in these images.
