Abstract

A method of selecting lens colors for eyeglasses. In the method, the colors of the skin, hair lips and pupils of a purchaser of eyeglasses are measured, and the angular positions of the measured colors on a hue circle are determined. Then, hues apart by specified angles from the measured colors are extracted as basic proposed colors. The purchaser is questioned to obtain words expressing an image for the lens color, and a color tone corresponding to each word is retrieved from a color name data base. For each color tone, the number of given words and weight of word are calculated. Further, hues which match the measured colors of the purchaser are determined based on the words. When certain basic proposed colors coincide with the thus determined hues, the numerical points for the certain basic proposed colors are increased. Additionally, it is inspected whether or not the basic proposed colors coincide with the color preference of the purchaser, based on the information of color preferences classified in terms of sex, age, district and country. The numerical points for the basic proposed colors are increased or decreased based on the results of the inspection. Finally, the basic proposed colors are arranged in order of the numerical points, and are presented before the purchaser.

Claims

1. A method of assisting in the selection of a lens color for eyeglasses, comprising the steps of:

measuring, as basic colors and using a calorimeter, colors of the skin, hair, lips and pupils of a person who will wear the eyeglasses and converting measured values into PCCS (Practical Color Coordinate System) values;

making a hue circle for each of the basic colors based on the PCCS values; and

extracting, as basic proposed colors, a plurality of colors on each of the hue circles, the proposed colors being apart by predetermined angles from the corresponding basic color.
