If everyone is beautiful, naked, and stacked, it’s Michelangelo. If the images have a dark background and everyone has tortured expressions on their faces, it’s Titian. Excel sheet with colored squares, it’s Mondrian. Dappled light and happy party-time people, it’s Renoir. If the paintings have tons of little people in them but otherwise seem normal, it’s Bruegel. If all the men look like cow-eyed curly-haired women, it’s Caravaggio. If everyone in the paintings has enormous asses, then it’s Rubens. If every painting is the face of a uni-browed woman, it’s Frida. If everything is highly-contrasted and sharp, sort of bluish, and everyone has gaunt bearded faces, it’s El Greco. If the painting could easily have a few chubby cupids or sheep added (or already has them), it’s Boucher.
