1660s, "crayons, chalk-like pigment used in crayons," from French pastel "crayon," from Italian pastello "a pastel," literally "material reduced to a paste," from Late Latin pastellus "dye from the leaves of the woad plant," diminutive of pasta (see pasta). Meaning "pale or light color" (like that of pastels) first recorded 1899. As an adjective from 1884.
