DNG in B&W?

I recently decided to shoot a few images in B&W in my K20D, capturing them in DNG and JPG. When I opened the DNG in my viewer they were in B&W too. I thought only the JPG would be impacted by the selection of monochrome and that the DNG would be in color.

I would think the same. Are you looking at a processed DNG or at the embedded preview? If just the preview, it does not surprise me as it is a jpg created by the camera. If you are looking at the DNG in Lightroom or other RAW processor then I don't know, that's weird.

Hm, I think DNG files have embedded previews, which are jpegs (and are affected by camera settings and in-camera digital filters), but the raw contains all the information. If you open the file in a raw editor you will probably have a switch "color / bw" and it will show you everything.

OK. I imported it into a folder and looked at the DNG in a viewer....not a processor. It opened into a large B&W image. Perhaps if it was an editor it would be different. I'll check it out. Thanks.

Yeah, they contain previews and I think most info of the settings. When I import to Lightroom at first they look like in camera Jpegs but when Lightroom finish reading the RAW files they go back to a neutral look instead. I think software like the Pentax supplied one keeps the Jpeg data as a default setting for the RAW file.

Some raw converters may use information from the image metadata as well. That's certainly possible, but definitely all the color data is there and available.

If you open it in Photoshop, or Lightroom or any photo editing software, you will get the color raw file and then will have the option to adjust it as you want, including making it b&w again. Simple photo viewers that come with operating systems will usually not read all the raw metadata. You need photo editing software for that.
