A set of gloss‐paint samples exhibiting large (10–25 CIE units) colour differences has been prepared. Visual assessments have been made under different viewing conditions. The results substantiate the view that visual assessments vary markedly with the size of sample and, together with earlier work (2), show that assessments also vary with the size of the colour difference. Thus, colour‐difference equations can correlate well with visual assessments only for given conditions. Existing equations apply best to conditions very different from those encountered in industry. It should not be too difficult to develop a more suitable equation for industrial use, given sufficient experimental data obtained under appropriate viewing conditions.
