Abstract: The color of a substantially spherical surface, such as that of a fruit, is measured by rotating the object about a vertical axis and projecting on the surface of the object, downwardly at 45*, an area of light that extends from the zenith to the equator of the object and is generally spherical triangular in shape, but differs from a spherical triangle in that the arc length s of the circles of latitude falling between the boundaries of the illuminated area is related as follows to the arc length s0 of the 45* circle of latitude:
