Your images are probably too dark?
digiKam uses a linear RAW conversion, which produces systematically too dark 
pictures with the side effect of colored highlights. If you go to the last 
tab "Lightness" you can adjust the non-linear conversion curve to create an 
almost satisfactory correction.

By the way, it is not the aim of RAW conversion to reproduce the JPEG with 
accuracy, it wouldn't make sense. RAW conversion is a development process 
that requires custom settings or human intervention.
