A color correction system and a method thereof are disclosed. A correction system according to the present invention includes an identification unit, a correction unit, and an adjustment module. The way of correction includes following steps: firstly the identification unit receives an image color data and identifies whether the image color data is a specific or a non-specific color data. Then the correction unit corrects the specific color data for display while the non-specific color data is adjusted by the adjustment module according to the color characteristics of the image output device. Therefore, the image data to be displayed is corrected and display quality of the image output device is improved.
