nice camera =) i was debating whether to get this, or the nikon d70, until i found this forum and blew all my saved up cash =P but i have to admit, flashlights have a certain element of more-instant-than-cameras-gratification going for them =)
this is slightly tricky though. looking through the pictures, the beam on the right seems more diffuse, and seems to have a very slight greenish tint, while the beam on the left sometimes has a bluish tint.
and here comes the tricky part. i don't know how much it matters, but you should know that you left your white balance on auto, which in turn would've changed the tint in every shot, at the whim of your camera. doesn't seem to be that much variation to the naked eye though, so maybe it didn't change it enough. but better to lock the WB next time =)
