without sounding sarcastic have you tried removing the UV filter and then taking some pictures of the same things when you used the UV filter?

What lense are you using? if you have another lense try it, is it producing the same issue?

If you provide some more info about the lense and the settings you are using people may be able to provide you with some suggestions.

Hope this helps out as a starting point.

I'd be more concerned about it being out of focus and perhaps with a little camera shake, noisy too at 1600ISO. 1/4 second is too long an exposure when in this close even with SR switched on. I doubt very much that your filter would have caused any colour cast, AWB will have removed any.

@ fletcher8, the exif data is intact so montyaus has provided all the details of lens and exposure.

The colour might be a result of being inside (mixed/artificial light). You can remove the colour cast easily enough in PP but as Gartmore said, focus/camera shake is more of an issue.

Best wishes Kris.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

I have to ask if SR is switched on ?

OK I have a K-x but I have SR on all the time so avoid camera shake
let the education continue

SR was switched on but shooting macro is a bit like using a 500mm lens in the shaky hand department!

SR gives you an extra couple of stops but that probably isn't enough in this instance.

Clarky and Mike-P are the resident macro experts around here and I'm pretty sure they are using flash most of the time ie. effective shutter speeds around 1/20000 sec.
