The paper describes studies that have been made of both visual and instrumental colour matching and attempts to measure those factors that must be taken into account when replacing visual with instrumental colour matching. The factors in visual colour matching examined are lighting source, viewing geometry, size of specimen, age, sex and colour‐vision defects of observer, and consistency of observers. Those in instrumental colour matching are lighting source, choice of 2° or 10° Standard Observer data, effect of viewing geometry, textile structure, lustre (or specular reflection), dichroism, fluorescence, metamerism of specimen, choice of colour‐difference formulae, and uniformity of visually uniform colour space. Mechanical and electrical reliability of instruments, short‐and long‐term reproducibility, and absolute and relative accuracies of instruments are discussed.
