The Simpsons defined the visual language of adult animation: a flat, hand-cel palette dominated by character-skin yellow, cobalt blue skies, and thick wobbly black outlines that never quite straighten. This system captures that irreverent cartoon energy — saturated broadcast colors, chunky rounded shapes, comic-book drop shadows, and the unmistakable feeling that everything was drawn by hand with a slightly shaky pen.

Apply it to projects that want instant warmth, humor, and pop-culture recognition without taking themselves too seriously.
