So howbout it you guys ever think of setting purity with that fancy color thing and then doing color spectrum measurement? It sure would be cool if a computer set purity and not our eye..... (Dam that squirrel)

Those "fancy devices" are much too slow to use for adjusting purity. For that you would need a fast-responding (though less accurate) device. Plus, you would need a multi-headed device that reads center, edge, and corner areas simultaneously. Only the production factory could afford such special instrumentation. In the home, the eye is the best instrumetn for adjusting purity.
