I am a newbie and not sure where to post this so here goes. I am trying to select the RGB sliders but it is grayed out. It works perfectly fine in Rebelle 2 but not Rebelle 3 which I have included a screenshot. Please advise how to fix.
please note at the moment, the RGB mode is only available as a Square palette. If you select Square instead of Circle in this same menu, you will be able to select RGB palette:
You're welcome! :)
