It takes the colour and light of whatever surrounds it. In a pale room it recedes. Against a dark wall it catches every surface behind it. At night, with the LED lights active, it becomes something else entirely. Music visible as well as audible, the interior illuminated, the keys moving, the sound filling the room.
Most are ordered in white, which frames the transparency without competing with it. Any RAL colour is available for the trim. The configurator holds the full range.
