Parent State ID: 68
Action Taken: change-color(robot1, white, black)
Action Reasoning: The last action taken was moving the robot left from tile_1-4 to tile_1-3. According to the logical conclusions, if the last action was a move, the next step should be to change the color of the paint gun. Currently, the robot is holding white, but the next tile to be painted (tile_0-2) should be black. Therefore, the best action is to change the color of the paint gun from white to black.
State Description: Robot1, located on tile_1-3, changes its paint gun color from white to black.
