Azure #007FFF
Azure is a color that is commonly compared to the color of the sky on a bright, clear day.
On the RGB color wheel, "azure" (color #007FFF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan.
In the X11 color system which became a standard for early web colors, azure is depicted as a pale cyan color.
Azure also describes the color of the mineral azurite, both in its natural form and as a pigment in various paint formulations. In order to preserve its deep color, azurite was ground coarsely. Fine-ground azurite produces a lighter, washed-out color. Traditionally, the pigment was considered unstable in oil paints, and was sometimes isolated from other colors and not mixed. Modern investigation of old paintings, however, shows that the pigment is very stable unless exposed to sulfur fumes.
In Russian, "голубой" (goluboj, azure or cyan) and "синий" (sinij, blue or navy blue) are not two shades of the same color, but distinguished in the way red and pink are distinct colors in English. A similar distinction exists between "azzurro" (azure, but used to indicate various shades of light blue) and "blu" (blue) in Italian and "ฟ้า (fah, sky blue) and น้ำเงิน (nam ngoen, blue) in Thai.[citation needed]
Azure may refer to:
Color or colour (see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, green, blue, and others. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates.
Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance.
