The TM-30 framework offers numerous metrics to describe how alight spectrum renders colors. These metrics are calculated usinga virtual set of reflectance functions intended to represent typicalreal-world object colors. In this work, we seek an analogous setrepresentative of paintings. The objective is to identify a minimalset of reflectance spectra that captures the maximum possiblespectral variability found in paintings.

Tasks: Collect Spectral Data on Pigments, statistically analyzereflectance functions within TM-30 framework
