Taking insights from the remote sensing field, in the recent decade, the advantages of hyperspectral imaging technology has been exploited for painting conservation. The estimation of pigment proportion in painting is a challenge that is due to the highly mixed nature of the paint layers, usually requiring to take into account the law of mixing colorants in turbid media. Having knowledge of some pigments and paint layers of the reverse side of The Scream (1893), in this study, we are exploring the feasibility of using a more simple linear model for its unmixing. The obtained results are promising, despite the simplicity of the mathematical model.
