Abstract

Radiative transfer theory concepts for color‐matching calculations of solid color coatings are reviewed. Two flux approximations to the exact radiative transfer theory for isotropic scatters are developed. The Kubelka‐Munk theory is discussed in the framework of two flux theories. A comparison is made between reflectances calculated from the Kubelka‐Munk, two flux approximate radiative transfer, and the exact radiative transfer theory for 45/0 and diffuse/near‐normal measuring geometries. A color‐matching method is presented for radiative transfer color‐matching calculations. This method, which can be implemented on a personal computer, is shown to give good color matches for the exact radiative transfer theory. The proposed color‐matching algorithm, which can be applied to all three models, gives results equivalent to established Kubelka‐Munk calculations. A comparison of the Kubelka‐Munk, two flux approximate radiative transfer, and exact radiative transfer color calculations shows them to give equivalent results for diffuse/near‐normal reflectance data. © 1997 John Wiley & Sons, Inc.
