| Abstract
In agreement with the relativistic model
proposed by Creutzfeldt et al., with the photometric rule (highest-luminance-as-white
rule) and with the influence of simultaneous contrast in the appearance
of a visual scene, we propose a first-stage mechanism yielding substantial
colour constancy. We have defined a set of first-stage colour descriptors
and test their utility in some numerical experiments. The statistical stability
of the descriptors for Munsell samples under different illuminants is good.
