OK, I envision this:
All four pips made from small splatters of paint forming pip shapes.
Spot cards: pips in semi-random order, as though formed from spilled paint. Supplemental ink splatters in colors from the Court cards (not red or black) small enough to be background and not take center stage from the pips.
Jacks: house painters with overalls, plaid shirts, painters' caps and roller brushes/house painting brushes.
Queens and Kings: fine art painters with painter's smocks, berets and medium/fine art brushes and pallets.
Jokers, spilled paint cans, rainbow-colored puddle, multicolor paw prints and two pets, a dog on one, a cat on the other, walking out of frame.
Background: painter's dropcloth canvas white with texture instead of plain white.
Feel free to plagiarize from me at will - hopefully this will spark your creativity a bit.
