1. A method for independently adjusting six color classes with the consideration of boundary colors on a display device comprises steps of:
detecting a plurality of pixels of a display device and calculating a first tint and a second tint of said pixels;
defining a first pixel, said first tint and second tint of said first pixel both locating in said color class;
defining a second pixel, said second pixel being close to said first pixel, and said first tint and said second tint of said second pixel both locating in the neighboring of said color class;
defining a third pixel, said third pixel presenting a pixel being neither said first pixel nor said second pixel;
finding the first pixel and second pixel on said display device and adjusting their colors; and
finding the third pixel on said display device and keeping its original color.
