Reflectance measurements of pigmented colorants.

Technical report PCG-06-02, Program of Computer Graphics, Cornell University, Sept 2006.

In this report, we present the results of an experimental study on the appearance of artists' paint over time. Paint samples were handmade to ensure material quality, using various pigment colorants and adhesive binding media. We present the results of our diffuse reflectance measurements, which show very significant perceptual differences in two different domains: how the appearance of paint changes over time; and how the appearance of one pigmented colorant varies when dispersed in different materials.
