What is Rainbow Paint?
Coverage challenge. The canvas is split into a grid (14 × 10 in Normal, 18 × 13 in Hard); each cell starts empty with a dark veil over it. Whenever motion is detected inside a cell, the cell "fills" with a rainbow color and stays filled for the rest of the round. Goal: 100 % coverage — near the end, the last unpainted spots pulse with golden rings so you can find and finish them instead of hunting blindly. Best time-to-completion is saved per difficulty. Encourages the kid to wave to the corners and edges of the camera view, not just stand in the middle. 90-second limit; if the timer runs out, the round ends as a "partial" with a percentage shown.
