Action Reasoning:
To progress towards painting tile_2-3 black as per the goal state while avoiding moving to already painted tiles, I will move the robot right from tile_1-2 to tile_1-3. This sets the robot up to paint the next clear tile below it.

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

Action Chosen:
right(robot1, tile_1-2, tile_1-3)
