Yellow
He is completely yellow with a short darker yellow/light brown mullet, dark yellow cowboy hat, and dark yellow cowboy suit. His jaw is wide and square-shaped, his face is simplistic with beady eyes and a wide grin, the rest of his body is thin and gangly.
Yellow is a well-meaning cowboy figure with a fixation on justice (most likely as an homage to his Undertale Soul counterpart, which represented justice). He is shown to be slightly unintelligent (for example, he makes a side comment during one of the ‘breaks’ in the cafe, that intends to comedically perpetuate the slight idiocy among the flowers) and is willing to go to drastic measures to enforce justice, whether that means inflicting harsh punishment on others or himself.
Yellow is also shown to be deeply infatuated with Blue, another one of the flowers.
He is yellow.
