Abstract

Based on the concept of the recognized visual space of illumination an experiment was conducted to measure the color appearance of a white test patch under the conditions where it was perceived as the object color and the light source color. The apparent color was measured by the elementary color naming method when it was viewed through a green color filter at its various positions between the patch and the eye in a room illuminated by a daylight type of lamps at the illuminance 20, 100, 500 or 1,600 1x. When the filter was placed close to the patch so that only the patch was seen through the filter, it appeared very green, but the amount of the chromaticity gradually decreased as the filter was moved to closer to th eye. The color finally returned to the original white when the filter was placed directly on the eye so that the entire visual field was covered by the green filter. A bright light was added on the test patch so that the appearance may become the light source color. The prediction for the apparent color based on the RVSI was that the color does not change in spite of the change in the visual field size through the green filter because the appearance cannot be controlled by the RVSI. The prediction was confirmed.
