Although having the same floor plan, the House and Senate chambers are decorated very differently, with the former in terra cotta and teal colors and the latter in blue and gold. An oval cartouche in the carpet at the entrance to the House chamber features the state flower, the apple blossom. Presiding over the house is the speaker, whose chair is behind a desk in the center with a plaster and paint version of the state coat of arms. The Senate chamber is somewhat smaller than the House. The president of the Senate is the lieutenant governor, who presides over sessions from a walnut rostrum at the front of the chamber. Both the House and the Senate use computerized voting systems, including wall-mounted screens that allow visitors to follow the voting and both also contain glass tiled ceilings that allow natural light to shine through etched glass panels to better light the room. These ceiling tiles feature the coats-of-arms of each state in the United States.
