The present invention provides a method and an apparatus for color calibration for calibrating an input color. A target color represented by a first coordinate pair (X 1 , Y 1 ). An input color, which is to be calibrated, is represented by a second coordinate pair (X 2 , Y 2 ) and can be adjusted with a chrominance parameter Pb and a chrominance parameter Pr. The first coordinate pair (X 1 , Y 1 ) and the second coordinate pair (X 2 , Y 2 ) are compared to obtain a state. In response to the state, Pb and Pr are adjusted until the second coordinate pair is equal to the first coordinate pair. Therefore, the input color is calibrated to match the target color.
