ABSTRACT:
Rotor blades for wind power installations of varying design configurations are known. Irrespective of the geometrical configuration of the rotor blades, all rotor blades are generally of a uniform color; typically. The rotor blades of the present invention better integrate a wind power installation into the landscape view, to improve environmental compatibility and to reduce the impact of the foreign body. That is to be achieved in particular in respect of installations with large rotor diameters (more than 40 m). A rotor blade comprising a rotor blade connection and a rotor blade tip and a surface which is arranged therebetween and which is divided into at least two regions which differ in respect of lightness and of which the lighter region is arranged closer to the rotor blade connection than the darker region which is of a natural shade and/or daylight sky shade and/or background shade.
