occasional magenta/green blotches

For the record, here's a link to a flickr JPEG of the photo I'm referring to above http://www.flickr.com/photos/sandyfleischmann/7792786418/sizes/o/in/set-72157630945647842/

I don't even see the slight magenta/green speckle under the roof looking at this version, but I recall I could see slight speckle looking at magnified versions of the RAW. In some thousand+ photos with the DP2Merrill this is truly the only time I noticed it in dark areas, but I think it is handled in the processing. I usually don't do any noise reduction... I don't recall exactly what I did processing this. It's all SPP, I don't use other software on my Sigma photos generally (except to crop).
Best regards, Sandy
