Teal

Teal is a dark cyan color. Its name comes from that of a bird, the Eurasian teal which has a similarly colored stripe on its head. The word is often used colloquially to refer to shades of cyan in general.

Darkness

Darkness is the condition resulting from a lack of illumination, or an absence of visible light.

Blue

Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. 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.
