Color Variant Slot

  "description": "The scheme slot a color variant puts behind the slide (bg1): a light or dark slot, or an accent. On an accent the text side is the light family (tx1 = light1, tx2 = light2) or the dark family (tx1 = dark1, tx2 = dark2), whichever text slot has the higher contrast on that accent; tx2 falls back to tx1's slot where it is under 4.5:1 on the accent, and bg2 is the accent itself.",
