The simplest form +## is a single color specification such as a @code{plot} format or an +## RGB-triple. In this case the polygon(s) will have one unique color. If +## @var{c} is a vector or matrix then the color data is first scaled using +## @code{caxis} and then indexed into the current colormap. A row vector will +## color each polygon (a column from matrices @var{x} and @var{y}) with a +## single computed color.
