Richard, might cross validation be an option for you? For instance, N-fold CV: Split the color samples into say N=10 subsets, build a profile from the union of the subsets #2,...,#N and verify this profile against the samples from subset #1, then build another profile from subsets #1,#3,...,#N and verify against subset #2, and so on, until all N profiles have been built and verified. Particulary for models with a larger number of parameters (e.g. LUT profiles), CV usually provides a more meaningful goodness of fit indication anyway than the residuals of the training set.
