For Boo’s room, the Pixar artists strove to create a little girl’s room that was both appealing and inviting. The room reflected her personality and creativity; an easel stood in the corner, her artwork covered the walls, and evidence of interrupted pretend-games were strewn on the floor. It needed to feel personal, but also a bit idealized, to work with the story point that her room resembled a simulator room in the scream factory.

Meticulous care went into choosing every detail of the door that needed to be distinguishable from every other door in existence. The curves of the outlined contours, the shapes and placement of the flowers, and color choices were all intentional and deliberate.
