Claim:
1. A computer-implemented method comprising: accessing a set of standard points in a standard color model; determining a set of components of each standard point in the set of standard points, the set of components representing a color in the standard color model corresponding to the standard point; receiving preference information for tuning the set of components; applying the preference information to the set of components of each standard point to generate a target color model, the target color model including a different target point corresponding to each standard point; determining transform coefficients for each pair of standard point and corresponding target point based on a relationship between the standard point and the corresponding target point by performing a polynomial fit operation to map the set of standard points to the target points, wherein the transform coefficients comprise polynomial coefficients of the polynomial fit operation; accessing a set of RAW points in a RAW color model; converting the set of RAW points to a second set of standard points in the standard color model; and converting the second set of standard points to a set of optimized points in the target color model using the transform coefficients.
