Hi, If I get this correctly, the card has grey patches as well as colour ones. The spot white balance tool adjusts white balance only, meaning that: - after adjustments, grey should be grey (neutral) - exposure is to be done independently - colour in non-grey patches, as well as the lightness of all patches are influenced by the camera profile. See darktable's documentation on that topic.
Of course I may have misunderstood something.
