{\emph{An extension by Patrick H\"acker}}


\begin{pgfplotslibrary}{colormaps}
	A small library providing a number of additional |colormap|s. Many of these |colormap|s originate from the free Matlab package ``SC --- powerful image rendering'' of Oliver Woodford.
	
	The purpose of this library is to provide further |colormap|s to all users and to provide some of them which are similar to those used by Matlab (\textregistered).

\begin{stylekey}{/pgfplots/colormap/autumn}
	A style which is equivalent to 
\begin{codeexample}[code only]
\pgfplotsset{
    /pgfplots/colormap={autumn}{rgb255=(255,0,0) rgb255=(255,255,0)}
