a 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. [70]
