A puppy portrait built from one rule: use every possible RGB color exactly once, all 16,777,216 of them, no repeats and none left out.
The face itself is simple and cheerful: a round head, two floppy ears, big round eyes with bright highlights, a small dark nose, a tongue peeking out over a smile, and a polka-dot bandana at the neck. But instead of the soft tans and browns you'd expect on a cartoon dog, the whole thing glows in shifting neon blues, greens, magentas, and oranges, with rainbow-edged rings around the eyes and ears. That's not a filter or a random effect. It's what happens when a normal, small color palette gets stretched out to cover the entire space of possible colors while keeping every shape and edge intact. The result is a picture that's still unmistakably a cute dog, just rendered as if it were made of pure, undiluted color.
