Abstract:
A method of testing the color quality of a colored gemstone is disclosed, taking the gem color as an entirety visually composed of different color components, whose total amount of color components is constant, so as to calculate hue-purity, color-strength and relative chromaticity of the gem color to test the color quality. The method comprises the following steps: (1) determining blackness, chromaticness and hue of the gem color; (2) calculating the hue-purity, color-strength and relative chromaticity in accordance with the blackness, chromaticness and hue; (3) finding a matching color in a pre-established standard color library for this specific gemstone according to the hue-purity, color-strength and relative chromaticity calculated in step (2), and use the name of the matching color to indicate the gem color and color quality.

Claim (Index 1):
A method of establishing a standard color library for a colored gemstone for testing the color quality of the colored gemstone, comprising: taking the color of the colored gemstone as an entirety visually composed of different color components, whose total amount of color components is constant, so as to calculate hue-purity, color-strength and relative chromaticity of said color to establish said standard color library for said colored gemstone, the steps are as follows:\n (1) collecting a plurality of colored gemstone samples as a training set; (2) determining blackness, chromaticness and hue of the color of said colored gemstone samples in said training set in a standard environment, wherein said color components include colored components and a white visual component, wherein said colored components include a black visual component and all chromatic visual components, wherein said blackness is the percentage content of said black visual component in said color of said colored gemstone, wherein said chromaticness is the percentage content of said chromatic visual components in said color of said colored gemstone; (3) calculating said hue-purity, said color-strength and said relative chromaticity of said color of said colored gemstone samples according to said blackness, said chromaticness and said hue: wherein said hue-purity represents the degree of purity or impurity and the offset color of said hue of said color of said colored gemstone calculated on the basis of one of the four psychophysical primary colors which are red, green, yellow, blue and the transitional intermediate colors between non-opposing psychophysical primary colors, using one of the following two calculation methods: (a), hue-purity is x % the secondary psychological primary color to the main psychological primary color, wherein x % is the percentage proportion of the secondary psychological primary color in the hue; and (b), hue-purity is y % the main psychological primary color to the transitional intermediate color, wherein y % is half of the difference between the percentage proportion of the main psychological primary color in the hue and the percentage proportion of the secondary psychological primary color in the hue; wherein: said main psychological primary color means the psychological primary color whose percentage proportion in said hue is more than 50%, and said secondary psychological primary color means the psychological primary color whose percentage proportion in said hue is less than 50%; when the percentage proportions of both psychological primary colors in said hue are 50%, then either of the psychological primary colors can be taken as said main psychological primary color, and the other can be taken as said secondary psychological primary color; said transitional intermediate colors are those of any two non-opposing psychological primary colors in the four psychological primary colors; wherein said color-strength is as follows: color-strength=blackness+chromaticness; wherein said relative chromaticity is as follows: relative chromaticity=chromaticness/color-strength; and (4) identifying, classifying, quantifying and defining the specific color represented by each colored gemstone sample in said training set according to said hue-purity, said color-strength and said relative chromaticity calculated in step (3) to get said standard color library for said colored gemstone.
