Fig. 9From: Tensor decomposition for painting analysis. Part 2: spatio-temporal simulationComparison of the CIE L*, C* coordinates between the spatio-temporal simulations at time step 8 (equivalent to 77 s of light exposure) and time step 1. Red depicts a positive change, while green a negative change. The negative difference prevails, which is in agreement with the colorimetric analysis of the microfading data (“Exploratory analysis” section)Back to article page
