Abstract

Designers of lights and reflectances seek--among other things--to create environments in which interchanges of artificial and representative natural daylights produce no noticeable effect on the appearance (or at least recognizability3 of colored objects. The present paper discusses some aspects of cooperative design whereby lighting and reflectances reveal the reflectances to be color-stable under interchange of a repertory of lights which therefore can be said to have good color-rendering properties. Of course, the designer’s world ought not to be restricted to degenerate solutions such as grey reflectances under low-pressure sodium lamps, but rather should contain natural daylights and reflectances.
