Abstract:
1. A method comprising: receiving, in a processor of a computer system, a pixel tuple of a digital image in a primary color space; designating the one of a first, second or third color value of the pixel having the highest value as a major color and designating the remaining two color values as minor colors; determining a ratio between a value of the major color and a sum of the values of the minor colors, and setting the pixel as a primary color if the ratio is less than or equal to a first threshold, otherwise setting the pixel as a non-primary color; and converting the pixel tuple into a value of a color palette scale, the color palette scale including a primary range for a visible light spectrum, a secondary range for a first composite spectrum corresponding to parallel values for the first, second and third color values, and a tertiary range for a second composite spectrum corresponding to parallel values for the first and second color values.
