I did not understand the problem at first, but I can reproduce it with my 
Nikon. First of all, it is not a good idea to take a image in B&W digitally. 
There are many more ways to do it later, but for the JPEG the color 
information is lost. There is currently no option in digiKam to specify that a 
thumbnail should be created from the RAW image. It uses the "fastest" source 
and that is the preview image. That was of course stored by the camera in B&W.
