Find the amounts of each primary, e1, e2, e3, needed to match some spectral signal, t. Those amounts, e1, e2, e3, describe the color of t. If you have some other spectral signal, s, and s matches t perceptually, then e1, e2, e3 will also match s, by Grassman s laws. Why this is useful it lets us: Predict the color of a new spectral signal Translate to representations using other primary lights. www.sliderbase.com   """  3380 _PPT10.3N`7 *wd    (    NoP?Rectangle 7_   &Goal: compute the color match for any color signal for any set of primary colors Examples of why you d want to do that: Want to paint a carton of Kodak film with the Kodak yellow color.
