(c3) according to described the 3rd color range solution obtaining, again corresponding described the first color coordinates of described the 3rd color range solution, the second color coordinates and the 3rd color coordinates are adjusted, on described color space, calculate the summation of the distance between distance between described the first color coordinates, described the 3rd color coordinates and described the second color coordinates, described the 3rd color coordinates for minimum, obtain the described first color range solution corresponding with described the first color GTG and the described second color range solution corresponding with described the second color GTG; And
(c4) according to described the first color range solution obtaining, again to corresponding described the first color coordinates of described the first color range solution, described the second color coordinates and described the 3rd color coordinates carry out as described in the method as shown in (c1) step recursively calculate, until described a plurality of the first color range solution, described a plurality of the second color range solutions and described a plurality of the 3rd color range solution converge to respectively described the first best color range solution, described the second best color range solution and described the 3rd best color range solution.
