Posterize vs pixel art

Posterize reduces colors only while keeping resolution (looks like a photo with simplified colors). Pixel art reduces resolution too (large visible pixels). Warhol's Marilyn-style is closer to posterization.

FAQ

Algorithm that picks K representative colors and clusters similar pixels โ€” most natural color reduction.

More colors = better?

No โ€” fewer colors strengthen the poster effect. 8 colors is balanced.
