User interface device for controlling a consumer load and light system using such user interface device

User interface device for controlling a consumer load, comprising:

• an input device (111);
• and
• a display device (112), the input device (111) and the display device (112) are arranged internested to each other in one common layer or in two layers respectively stacked on each other, and
• a color layer (115) being at least a semi-transparent and including at least one of a first colored scale (210) indicating a first range of values adjustable by an user input on the input device (111) via the first colored scale (210), a second scale (220) indicating a second range of values adjustable by an user input on the second scale (220) and/or a background area (230, 235);
• wherein the color layer (115) is placed in front of the display device (112), or in front of the common layer,
• wherein the display device (112) is adapted to display at least a first feedback indicator (215) within the first colored scale (210) indicating the current value of the first range of values output by the user interface device to the consumer load (545),
• wherein at least one light element (120) of the display device is arranged behind the color layer (115) to display at least one of the first and/or second feedback indicators (215, 225) within one of the first colored scale (210) or the second scale (220) on the color layer (115).
