Abstract

Neutral areas on color film were selected by a visual color matching technique as a basis for comparing real observers with the CIE standard observer. Data from 29 observers show low precision of visual selection as compared to standard physical techniques, and possible deviance from the CIE standard observer in the blue direction. A comparison of Stiles’ tentative mean observer with the CIE standard observer showed that the latter is the more representative of our real observers.
