With the default settings for white balance and color calibration, colors are off for Sigma DNG images shot with a foveon sensor (i.e. Sigma SD & DP series).
The effect can be avoided when setting color calibration to 'bypass' and white balance to 'as shot' (==first 'camera'-icon in the 'white balanace' tab). But unfortunately the last step (set white balance to 'as shot') can't be saved in a camera specific default because only temperature and tint are saved in the default.
These facts make processing Sigma SD&DP images a royal pain.
Steps to reproduce
import a Sigma DNG image
== yuck, everything's green and yellow.
Expected behavior
Darktable should either display correct colors from the beginning, OR save the fact that white balance is set to "as shot" in the white balance default if the camera icon was clicked.
