Morty Smith's T-Shirt

How this color came to be

Rick and Morty premiered on Adult Swim in late 2013, created by Justin Roiland and Dan Harmon. Morty Smith — the fourteen-year-old grandson who reluctantly accompanies his alcoholic scientist grandfather on multidimensional adventures — wears the same outfit in nearly every episode: brown pants, white sneakers, and a pale yellow T-shirt. The color choice was deliberately understated: where most adult-animation protagonists wear bold primary colors, Morty's shirt is soft enough to fade into the background, mirroring the character's own anxious, unassertive personality.

The hex breaks down to HSB(57°, 57%, 100%). Brightness is maxed at 100%, but saturation sits at only 57% — well below typical cartoon-clothing default. The hue at 57° is just one degree cooler than SpongeBob's 56°, but the lowered saturation completely changes how the color reads. SpongeBob's body, at HSB(56°, 100%, 100%), is a fully aggressive yellow; Morty's shirt, at the same brightness with much less saturation, reads as pale butter-yellow or cream-yellow. It's a yellow that's been "diluted" without losing its yellow identity.

The most common wrong answer is reaching for too much saturation. Instinct on a yellow T-shirt lands near 80% saturation; Morty lives 25 points below that. The other trap is going pale on brightness — but Morty's brightness is genuinely at 100%. The combination of "max brightness, mid saturation" is unusual and feels wrong while you're dialing it in. Match by pinning brightness to the very top, then pulling saturation back to the high 50s, with hue settled around 55–58°.
