Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model (traditional colour theory). It lies between violet and cyan on the spectrum of visible light. The term ''blue'' generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495  nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments. In the eighth century Chinese artists used cobalt blue to colour fine bl ...

It describes the economic, political, and social theories and movements associated with the implementation of such systems. Social ownership can take various forms, including public, community, collective, cooperative, or employee.: "Just as private ownership defines capitalism, social ownership defines socialism. The essential characteristic of socialism in theory is that it destroys social hierarchies, and therefore leads to a politically and economically egalitarian society. Two closely related consequences follow. First, every individual is entitled to an equal ownership share that earns an aliquot part of the total social dividend ... Second, in order to eliminate social hierarchy in the workplace, enterprises are run by those employed, and not by the representatives of pr ...
