I was wondering if the “Primary” color was left out of the panel controls color style on purpose or if it maybe was over looked. I ask that because everything else seems to have a primary color style option but the panel. I was hoping to see if this was something that may be added in if it was meant to be excluded from the color style.
Which version of the SPARK UI Toolkit are you using?
I was able to successfully set the Panel control to use the Primary color style in all BPM versions with the latest release version 4.4.3. However, I was able to replicate this issue with an older version of the Toolkit.
