Abstract
A visual colorimeter was designed to implement a new model for the det ermination of color-matching functions developed in the Munsell Color Science Laboratory. An instrument utilizing laser primaries was origin ally developed. The instrument was later improved to incorporate CRT p rimaries and seven interference filters to make matches to simulated d aylight in a 2-degrees bipartite field. The system was designed to min imize the strain on observers. Color-matching functions of naive obser vers can be measured in approximately 30 minutes. Results from an indi vidual observer correlate well with data collected on the National Res earch Council of Canada's Trichromator. Part II of this article gives the color-matching functions results for 18 observers and 20 repetitio ns by a single observer.
