Parent State ID: 99
Action Taken: change-color(robot1, white, black)
Action Reasoning: The robot is currently on tile_1-4, holding white paint. The goal is to achieve an alternating color pattern starting with black on the first row. The last action was "paint-up" on tile_0-4, which is now painted white. The next logical step is to change the color of the paint gun to black, as the next tile (0,3) needs to be painted black. This aligns with the rule that if the last action was a move, we should change the color of the paint gun.
State Description: Robot1 is now holding black paint while remaining on tile_1-4.
