The emperor (yellow=7) parades down a central avenue. The crowd (blue=4) lines both sides, all showing approval (value=4). A single child (red=1) stands in the crowd. In the masked grid, the child speaks the truth — the child's cell changes to value 1 (standing out), and the crowd cells nearest the child also begin changing to 1 as the truth spreads, while the emperor remains oblivious at value 7.
