This paper analyzes color rendering problems arising in computer imaging of scenes with complex optical properties. The sources of these errors for imagery constructed on the basis of the RGB space are analyzed and an efficient and correct algorithm is proposed for spectral imagery. These solutions are applied to problems of direct stochastic and inverse deterministic ray tracing. In addition, complex scenes with mixed optical properties defined in different (including RGB) models are proposed to be treated by an efficient and correct algorithm for reducing all optical properties into a single spectral model.
