Historically, a person who made or sold paint and pigments; a colormaker or paint supplier.
From 'colour' (noun) + 'man' (suffix indicating a person in a profession). This is a traditional occupational surname pattern common in English, like 'blacksmith' or 'miller'.
The 'colourman' profession was crucial to art history—artists like Monet and Cézanne depended on colormen to develop new synthetic pigments, and without innovations from paint suppliers, the Impressionist revolution literally couldn't have happened!
Historical trades defaulted to masculine terms; 'colourman' refers to supplier/worker in paint/pigment industry. Male-coded despite being a profession both genders have always worked.
Use 'color supplier' or 'colorist' to remain neutral. If referring to a specific person, match their identity.

Women artists and pigment manufacturers have long been erased from art history; acknowledging women colourmakers (like those in medieval illumination and modern cosmetics) corrects this oversight.
