A colored pencil (American English), coloured pencil (Commonwealth English),[1] colour pencil (Indian English), map pencil,[2] pencil crayon, or coloured/colouring lead (Canadian English, Newfoundland English) is a type of pencil constructed of a narrow, pigmented core encased in a wooden cylindrical case. Unlike graphite and charcoal pencils, colored pencils' cores are wax- or oil-based and contain varying proportions of pigments, additives, and binding agents.[3] Water-soluble (watercolor) pencils and pastel pencils are also manufactured as well as colored cores for mechanical pencils.
Colored pencils are made in a wide range of price, quality and usability, from student-grade to professional-grade. Concentration of pigments in the core, lightfastness of the pigments, durability of the colored pencil, and softness of the core are some determinants of a brand's quality and, consequently, its market price. There is no general quality difference between wax/oil-based and water-soluble colored pencils, although some manufacturers rate their water-soluble pencils as less lightfast than their similar wax/oil-based pencils. Colored pencils are commonly stored in pencil cases to prevent damage.
Despite colored pencils' existence for more than a century, the art world has historically treated the medium with less admiration than other art media. However, the discovery of new techniques and methods, the development of lightfast pencils, and the formation of authoritative organizations is better enabling colored pencils to compete with other media. Additionally, colored pencils are more affordable, cleaner, and simpler compared to other media.[4]
