1. A color selection input device comprising:
- a hue selection object representing selectable colors with hue gradation along a direction thereof;
a saturation selection object representing a selectable saturation gradation along a direction thereof;
wherein the hue selection object and the saturation selection object are arranged to form fixed overlapping region, and wherein the saturation selection object is transparent and shaded such that the saturation selection object varies from fully transparent to fully white in a plane by including portions of the saturation selection object in the plane that have different colors for visualizing a hue and saturation selection in the overlapping region; and
an electronic circuit configured to detect positions of the hue selection object and the saturation selection object and to generate a color selection signal that depends on the detected positions,wherein the hue selection object and the saturation selection object are implemented by respective selection wheels, wherein one of the selection wheels has a smaller diameter than the other selection wheel and is arranged on the other selection wheel to form an overlapping area comprising the overlapping region.

Abstract
The invention relates to color selection input, for example by means of color selection wheels or pads, particularly for a lighting system. An embodiment of the invention provides a color selection input device (10) comprising
- hue selection means (12) representing selectable colors in terms of hue gradation along a direction thereof,
- saturation selection means (14) representing a selectable saturation gradation along a direction thereof, wherein
- the hue selection means (12) and the saturation selection means (14) are arranged such that they comprise an overlapping region (16) and the saturation selection means (14) are transparent and shaded from fully transparent to fully white for visualizing a hue and saturation selection in the overlapping region (16), and
- means (18) for detecting the positions of the hue selection means (12) and the saturation selection means (14) and generating a color selection signal (19) depending on the detected positions. This may make navigating through the hue and saturation color space more convenient and intuitive for users.
