UV Filter

I think I'm a bit confused about a filter issue. I have two Optica filters, one labeled UV and the other IR. I would assume that these filter transmitt UV and IR light respectively. The odd thing is when I shot images of Venus last night, the IR image turned out dark blue and the UV image turned out orange. To me, that sounds backwards, or am I missing something? I think I'd like to get a good UV filter for planetary imaging...is the Lumicon 48mm UV-370 UV Filter what I should be looking at for my C925 and CCD imaging or does someone have another suggestion.

Thanks a bunch!!

From what I understand, UV and IR filters reject or block the UV and IR rather than transmit it.
