Blue is one of the three primary colours in the RYB colour model (traditional colour theory), as well as in the RGB (additive) colour model. [ 2] 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 that's between approximately ...
Air force blue, also known as RAF blue, is used by the Royal Air Force, the first air force to choose an "air force blue" color by which to identify itself, in 1920. The color "air force blue" is a medium tone of azure since it has a hue code of 204 which is a hue code between 195 and 225, signifying a tone of azure.
For practical additive color models, an equal superposition of all primaries results in neutral (gray or white). In the RGB model, an equal mixture of red and green is yellow, an equal mixture of green and blue is cyan and an equal mixture of blue and red is magenta. [ 1]: 4.2 Yellow, cyan and magenta are the secondary colors of the RGB model.
Blue pigments are natural or synthetic materials, usually made from minerals and insoluble with water, used to make the blue colors in painting and other arts. The raw material of the earliest blue pigment was lapis lazuli from mines in Afghanistan, that was refined into the pigment ultramarine. Since the late 18th and 19th century, blue ...
RGB color model. The RGB color model is an additive color model [ 1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
Cobalt blue is a blue pigment made by sintering cobalt (II) oxide with aluminium (III) oxide (alumina) at 1200 °C. Chemically, cobalt blue pigment is cobalt (II) oxide-aluminium oxide, or cobalt (II) aluminate, CoAl 2 O 4. Cobalt blue is lighter and less intense than the (iron-cyanide based) pigment Prussian blue.
