Abstract
Predicting material color shifts due to weathering. A color formulation tool determines the concentration of colorants from a color standard. The color formulation tool obtains weathered optical parameters for the color standard from a color database and predicts the color of the color standard from the colorant concentrations and weathered optical parameters.
