Fig. 9From: Reconstructing Van Gogh’s palette to determine the optical characteristics of his paintsa Reflectance curves for ultramarine blue reconstruction paints, both as measured and as calculated with Kubelka–Munk theory after optimization of K and S parameters. Percentages refer to mixtures defined in Fig. 2. b Calculated Kubelka–Munk K and S values for reconstruction paint ultramarine blue, compared to experimental values published by Latour et al.
