Action Reasoning:
The robot is currently on tile_0-4 and holding black, which matches the goal color for tile_1-4. The best action is to paint tile_1-4 black, moving us closer to the goal state.

New State Description:
Robot1 is standing on tile_0-4, holding the color black. Tile_1-4 is now painted black and is no longer clear. Tile_0-4 remains occupied by the robot. All other tiles remain unchanged.
