Abstract
A blade for a wind turbine has a surface with a first color band and a second color band and a third color band thereon in spaced relationship to each other. A luminescent band extends in the space between said first, second and third color bands. The first, second and third color bands are of different colors. The luminescent band extends around a periphery of each of first, second and third color bands. The first color band is a red color. The second color band is a white color. The third color band is a blue color.
