This article describes the design, construction, and evaluation of a visual colorimeter for use in studies of color perception in the natural environment. The colorimeter is portable, has a low power consumption, and produces luminances typical of those found outdoors. An asymmetric binocular‐matching procedure is used to match the colors of natural objects. The performance of the colorimeter was tested by comparing chromaticities of matches of colored papers to spectrophotometric measurements.
