Why isn't Elmo purple with pink and blue polka dots?

Elmo is designed as a bright red character to stand out and appeal to preschoolers, embodying a playful and energetic personality. The choice of color and simple design aligns with the show's educational goals, making him easily recognizable and relatable. A purple character with pink and blue polka dots might not convey the same immediate warmth and friendliness that Elmo represents. Moreover, maintaining distinct colors for characters helps in creating a cohesive visual identity within the Sesame Street brand.
