A method for pixel color correction includes the steps of determining a gray degree of a designated pixel; generating an adjusted color correction matrix according to the gray degree of the designated pixel; and applying the adjusted color correction matrix to the designated pixel to correct color errors of the designated pixel. The gray degree is generated according to a ratio of the chrominance information to the luminance information. A weighted sum of a reference color correction matrix and a unity matrix is calculated to generate the adjusted color correction matrix, and weighting factors of the reference color correction matrix and the unity matrix are determined by the gray degree, wherein the unity matrix is a fundamental matrix without color correction.
