Cerulean

The color cerulean, or caerulean, is a variety of the hue of blue that may range from a light azure blue to a more intense sky blue. Cerulean may also be mixed with the hue of green. The first recorded use of cerulean as a color name in English was in 1590. The word is derived from the Latin word caeruleus, "dark blue, blue, or blue-green", which in turn probably derives from caerulum, diminutive of caelum, "heaven, sky".
