1. A method for adjusting a target color in a device independent color space into a color gamut and determining corresponding device dependent color space coordinates comprising: moving the color along a gravitational potential gradient path to an intersection point where the path intersects the color gamut; wherein a simplified triangle mesh representation of the color gamut is used for gravitational potential gradient calculations; a fine triangle mesh representation of the color gamut is used for determining said intersection point; and computing corresponding device dependent color space coordinates at said intersection point.
