+The color to use in the shaded portion of the graph. All valid color strings defined for use by @code{PGFPLOTS/Ti}@i{k}@code{Z} are valid. A list of defined colors is: @code{`red'}, @code{`green'}, @code{`blue'}, @code{`cyan'}, @code{`magenta'}, @code{`yellow'}, @code{`black'}, @code{`gray'}, @code{`white'}, @code{`darkgray'}, @code{`lightgray'}, @code{`brown'}, @code{`lime'}, @code{`olive'}, @code{`orange'}, @code{`pink'}, @code{`purple'}, @code{`teal'}, and @code{`violet'}. Furthermore, You can use combinations of these colors. For example, if you wanted a color that is @math{20\%} green and @math{80\%} purple, you could pass the string @code{`green!20!purple'}. You can also use RGB colors, following the syntax: @code{`rgb,255:red,231;green,84;blue,121'} which corresponds to the RGB color @code{(231;84;121)}. More examples are available in the section 4.7.5 of the @code{PGFPLOTS/Ti}@i{k}@code{Z} manual, revision 1.10. Default: @code{`green'}
