you can give the CMY values in the range from 0..255 to specify any color you want.
Besides the color mixing possibility of this fixture (lamp) it can also Pan and Tilt. So move the head around and upside down.
Because each lamp is inside another hotel room it gives some very nice effects if you let the fixture Pan and Tilt. It creates a more spacious result, giving it more depth then just a color.
anyway, hope we can provide some pixtures and movies soon.
