Winnie the witch has a black house. The interior of the house is also black, just like her cat Wilbur. When Wilbur closes his eyes to doze off, he disappears into the background of Winnie's home, and she accidentally tramples him. Winnie changes Wilbur's color to bright green, but when he's outside she can't see him against the green grass and again trips over him. She then waves her wand over him five times and turns him into five colors. Wilbur looks ridiculous and does not like his new look. Winnie does not want her cat to be sad and changes him back to black, instead she turns her house into many colors so Wilbur will be visible.
