In this study a simplified Kubelka–Munk model is proposed for colour matching purposes. Opaque glazes were prepared to determine theabsorption optical constants from the reflectance curves measured with a spectrophotometer. After the physical and chemical characterization ofthe glaze components (frit and pigments), to analyze the spectrophotometric results a simplification of the Kubelka–Munk model was suggested.To experimentally verify the model, two target green colour were reproduced in laboratory by adding in an opaque glaze a yellow praseodymiumdopedzircon ((Zr,Pr)SiO4) and blue vanadium-doped zircon ((Zr,V)SiO4) pigments. The results were in good agreement with the experimentalreflectance curves and the prediction of colour green glazes was possible with a reduced number of experiments.
