Calamine Blue

Calamine

Calamine, also known as calamine lotion, is a medication made from a combination of powdered zinc oxide and 0.5% ferric oxide (Fe2O3) that is used to treat mild itching. It benefits sunburn, insect bites, allergenic irritation, and other mild skin conditions, and may also help dry out secretions resulting from skin irritation. Calamine has also been used as a treatment for acne and acne scars, although it may damage the barrier of sensitive skin. Its name comes from calamine, a historic name for the zinc ores smithsonite and hemimorphite.

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.
