I gotta say that Pentax seems to have got it right with colors. If me, the photog, gets it right, the K100D does so too. I often slide the color to the left, to the right, and end up just were it was in the first place (WB daylight jpgs foremost).
This helps for estimating the lenses' color rendering characteristics (like Frank said, lots of difference).
One special question for me would be: How cool can that camera be?
What I mean by this is described here,

Conclusion thereof would be that any Pentax or Nikon have 'daylight balanced' sensors and therefore you end up with a light blue filter in the described circumstances. Maybe just take a Sigma cam and take that red filter out :-)
