Medieval and Manuscripts
Azure is the color between cyan and blue on the color wheel. It is often described as the color of the sky on a clear day. On the RGB color wheel, "azure" (hexadecimal #0080FF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a 20% of green light to a 100% of blue light. In the X11 color system, which became a model for early web colors, azure is depicted as a pale cyan or white cyan.
