Starry night painting session went sideways but the kids loved it

Tried to do Van Gogh's Starry Night recreation with my twins (4yo) yesterday afternoon. I bought these cheap acrylic paints from Amazon and basically gave them paintbrushes and let them go to town on a big canvas. It looks NOTHING like the original (blue and yellow mixed into brown mud tbh) but they were engaged for two whole hours and actually made a second painting after. Hung it up on the fridge anyway because the process was way more valuable than the product. Anyone else do art projects where you just expect chaos?
