A color reference data base and method of making same by preparing colored swatches on photographic media corresponding to a plurality of color points located in the data base working area and placing each such colored swatch at its respective point within the working area, such colored swatches being prepared by selecting a set of up to three colored filters the color constituents of which, when located in the working area, determine a filter triangle such that the color point of the colored swatch or the complement thereof lies within or on the filtered triangle, determining the saturation time for each colored filter for the particular photographic media being used, computing the filter percentage needed for each colored filter, multiplying the saturation time for each colored filter by its respective filter percentage to determine its exposure time, exposing the photographic media through each colored filter for its respective exposure time, and developing the exposed photographic media.
