A method of color index searching in a color picture. An estimated color index X and an estimated range Y are obtained. An index range is set according to the estimated color index X and the estimated range Y. A color dimension of color signals corresponding to the index range is altered to make the color signals responding to the color dimension alteration. It is determined whether a designated region is responsive. If the designated region is not responsive, the estimated color index X is changed to update the index range for another color dimension alteration. If the designated region is responsive, the estimated range Y is reduced to update the index range for another color dimension alteration. If the estimated range reaches an acceptable range, the color index of the designated regions is found.
