 % There are proprietary models (like \Index{Pantone} or \Index{HKS}) that provide finite sets of colors (often called \emph{\Index{spot color}s}), where the user has to choose from without caring about parametrisations; on the other hand, there are parameter-driven models like \Model{gray}, \Model{rgb}, and \Model{cmyk}, that aim to represent large finite or even (theoretically) infinite sets of colors, built on very small subsets of base colors and rules, how to construct other colors from these base colors.
 % For example, a large range of colors can be constructed by linear combinations of the base colors \Color{red}, \Color{green}, and \Color{blue}.
 % On the other hand, usually \Index{spot color}s can only be \emph{approximated} by parameter values in models like \Model{cmyk} or \Model{rgb}; the original colors are being physically mixed even dependent on the targeted kind of paper.
-% Finally, there are certain colors like \Color{gold} and \Color{silver} that are hardly reproducable by any parameter-driven color model on standard ink or laser printers.
