Action Reasoning:
Robot1 is currently on tile_1-1, and tile_2-1 directly below is already painted. The next feasible step is to move Robot1 right to tile_1-2, which is clear, so it can directly access and paint tile_2-2 below with white, matching its held color.

New State Description:
Tile tile_0-1 is clear. Tile tile_0-2 is clear. Tile tile_0-3 is clear. Tile tile_1-1 is clear. Tile tile_1-2 is occupied by robot1. Tile tile_1-3 is clear. Tile tile_2-1 is painted black. Tile tile_2-2 is painted white. Tile tile_2-3 is painted black. Robot1 is on tile_1-2, holding color white. Colors white and black are available for switching.

Action Chosen:
