A method for providing a mapping from apparent color to actual color for an image capture device including capturing an image of a reference color chart having a plurality of color patches using the image capture device, wherein each color patch has an associated reference color, measuring the apparent color of the plurality of color patches in the captured image, selecting a plurality of control points representing different hue values within a circular hue space, determining an angular offset for each control point such that the distance between a transformed apparent color and the reference color for each color patch is minimized, the angular offset representing a hue correction, wherein interpolation of the angular offsets for the control points provides a mapping from apparent color to actual color for the image capture device. |
