The Shelf Competition Problem
The retail shelf is a competitive visual field in a way that no other context is. Dozens of products in the same category occupy a single viewing frame simultaneously, all competing for the same 0.3-second attention scan. The color decisions that work in isolation — on a presentation slide or in a mood board — are tested under completely different conditions on the shelf. A beautiful, harmonious color palette may be invisible on a shelf surrounded by louder, simpler competitors. The constraint that packaging color must navigate is not 'does this look good' but 'does this win at 3 meters when surrounded by 30 competitors.'
