Just like his family, Bart Simpson from The Simpsons is also yellow. Yellow is one of the most visible colors to the human eye because of the way our eyes process light. It's also known to be a color that represents optimism and joy. It makes total sense that the Simpson family, who have spread so much joy in their 30-year history, are painted this color!

"When you're flicking through channels with your remote control, and a flash of yellow goes by, you'll know you're watching The Simpsons," Groening once said when asked about why he chose the color.^[1]

Bart wears a bright red-orange shirt, vivid blue shorts, and blue sneakers with white socks. Blue and orange are complementary colors, creating an energizing effect that fits Bart's personality. He's known for his mischievousness, rebelliousness, and disregard for authority.
