Saw this Playful Palette's presentation a couple of days ago. It is from Adobe. If this could be added to Krita, it would take it to the next level.

That is an very interesting way to visualize a color dish mixer with blobs and gradients.

kudos to anyone that trys to implement one of these in krita!
