Abstract
A color conversion method for preferred color tones to change original color in a color image into a preferred one. The invention first sets chromaticity of the selecting original color and corresponding preferred color, then takes them as the basic points to establish a tone action space of the two color according to a color tone action distance. The two spaces are then joined to form a color conversion space and to determine a vector from the original color to the preferred color for converting the colors in the color conversion space into the new color. Finally, the color conversions from the original color to the new color are made to generate a new color image with the preferred color tone. The invention only converts the original colors in the color conversion space into new colors to get a new color image with preferred color tones. The selecting original color and corresponding preferred color pair can be plural in the invention.
