1. A pretty blue color made by the Crayola Crayon Company.

The name "Cerulean" comes from Latin caelum = sky (this is the most likely source).

Discovered in 1805 by Andreas Höpfner, the pigment originally referred to as cerulean blue (or corruleum blue) was first marketed in 1860 as "coeruleum" by George Rowney of the United Kingdom. The primary chemical constituent of the pigment is cobalt(II) stannate.

2. The color usually used to describe Naruto Uzumaki's (from the Japanese animation NARUTO by Kishimoto Masashi) eye color.

The color of Matt's room. Also a color located in a 96 box of Crayola crayons. It's a very nice shade of blue that both males and females of all ages will enjoy. Depending on your size you may or may not enjoy the color cerulean as much. Usually the color is a color of hope and determination for adolescents when addressing their feelings.

Cerulean blue is by far the best crayola crayon color. It is a bright blue hue, and can be used to create startling depictions of the ocean, the american flag, and blue man group.

It can describe mood as well

In classical times, cerulean was used to describe blue pigments, particularly mixtures of copper and cobaltous oxides.

The first recorded use of cerulean as a color name in English was in 1590.1 The word is probably derived from the Latin word caeruleus, "dark blue, blue or blue-green", which in turn probably derives from caelulum, diminutive of caelum, "heaven, sky".2

This is often used to sound smarter in front of someone who doesn't know better. Also used in front of women, so they don't catch on to what you are saying.

A pro-ana board that claims to be pro-suppport. But in reality supports fasts, has thinspiration and tips and tricks now defined as meeting yourself halfway.
It is run by mainly whiny, emo girls between the ages of 16-21 who cry about life and how their parents don't understand, oh how nobody knows about their eating disorders or rather imagined eating disorders.
Recently they have been featured in Faces of Pro-ana
Which created a wave of furor on another board Mama Vision where the members of CB showed their true colours.
