How bug is working? First, need implement HCG sliders to Krita. After you can test HSV2. If moves in wrong direction - you found bug.
At this point I would rather you started to prepare it for building on Krita 3.0 as we're not supporting 2.9 anymore.
New patch. Not replaced HSV2, just added new color model HCG, with correct gradient. https://phabricator.kde.org/D1374
The patch was abandoned, apparently, so closing the issue
