Colored pencils can vary greatly in terms of quality and usability; concentration of pigments in the wax core, lightfastness of the pigments, durability of the colored pencil, softness of the lead, and range of colors are indicators of a brand’s quality and, consequently, its market price. Typically, water-soluble and oil-based colored pencils are considered to be a higher quality than their wax-based counterparts, but for many artists, these differences are a matter of preference. Rising popularity of colored pencils as an art medium sparked the beginning of the Colored Pencil Society of America (CPSA). According to its website, “[CPSA] was founded in 1990 as a nonprofit organization dedicated to artists over 18 years of age working with colored pencil”.[2] The CPSA not only promotes colored pencil art as fine art, but also strives to set lightfastness standards for colored pencil manufacturers.
