A user interface device ( 100 ) for controlling a light source ( 120 ) includes a central button ( 140 ) configured to change color of light emitted from the light source ( 120 ) when actuated by circumnavigating a color wheel; a saturation button ( 145, 150 ) configured to change saturation of the light when actuated; and a hue button ( 155, 160 ) configured to adjust hue of said light when actuated. The central, saturation and hue buttons may be discrete buttons or integrated into a single button ( 210 ). The user interface device ( 100 ) further includes a brightness button ( 110 ) located at a spaced distance from the central button ( 140 ) and is configured to change intensity of the light when actuated.
