Eloise is a young artist who loves to mix colors. Sitting on the front stoop of her house, she tells her neighbor, Rainbow Joe, how she combines red and white to make fish, and red and blue to make monkeys. Rainbow Joe explains that even though he is blind he can imagine colors. Not only that, he can make them sing. Eloise's mother says the blind man is just dreaming. It isn't until Rainbow Joe takes out his saxophone and plays colors that Mama and Eloise can see them. Big red notes and little yellow notes begin to fly as music fills the sky.
