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