An illuminated control (1) comprising an opaque front member (30) with transparent symbols (35; 35-1, 35-2), a settable control member (50) and at least one light source (60; 60-1, 60-2) is disclosed. The light source (60; 60-1, 60-2) is able to illuminate the symbols (35; 35-1, 35-2) and an optional indicator (52; 52-1, 52-2) in the control member (50) both with a color, preferably greenish, which is adapted for lighted environments, such as in daylight, and a color, preferably bluish or reddish, which is adapted for dark environments, such as during night. In addition, the night-adapted color should not substantially impair the scotopic vision of an operator reading the control (1). By switching between illumination color, a clear and reliable reading of the control (1) and a setting of the control member (50) in all environmental conditions are obtainable.
