1. A method of adjusting color, characterized in that: the method comprises: measuring a plurality of tristimulus sets at various white grayscales on a LCD panel; converting the plurality of tristimulus sets into a plurality of chromatic sets (x n , y n ), where n=0, 1, 2,. .. , 255; among the plurality of chromatic sets, judging a pth chromatic set (x p , y p ) as a breakpoint, where x p−1 −x p <0, x p −x p+1 =0, y p−1 −y p <0, y p −y p+1 =0; and based on the pth chromatic set (x p , y p ), determining a plurality of target chromatic sets (Nx n , Ny n ) at from the grayscale 0 to the grayscale p, where Nx n = x 0 + ( x 255 - x 0 ) · [ 1 - exp ( 1 - p n ) ] , Ny n = y 0 + ( y 255 - y 0 ) · [ 1 - exp ( 1 - p n ) ] , n=0, 1,. .. , p and exp denotes to an exponential function.
