There is provided a method and apparatus for image color enhancement, wherein the method comprises the following steps: S1, collecting color components of an image, converting the color components from a RGB space into a HSV space, and obtaining parameters in the HSV space as hue, saturation, and value respectively; S2, performing gain operations selectively on the saturation and the value by judging the saturation in the HSV space; S3, converting the obtained parameters in the HSV space back into the RGB space. In the above method for image color enhancement, after the color components are converted into the HSV space, firstly, the saturation value is judged, and the gain operations are performed selectively by utilizing the gain function according to the judgment result.
