[colorbrewer] Colormap `PuOr` defined in reverse order

The colormap PuOr is not from Purple (low) to Orange (high) as expected, but from Orange to Purple.

A fix would be to use

\pgfutil@definecolor{PuOr-O}{RGB}{127,59,8} \pgfutil@definecolor{PuOr-N}{RGB}{179,88,6} \pgfutil@definecolor{PuOr-M}{RGB}{230,97,1} \pgfutil@definecolor{PuOr-L}{RGB}{224,130,20} \pgfutil@definecolor{PuOr-K}{RGB}{241,163,64} \pgfutil@definecolor{PuOr-J}{RGB}{253,184,99} \pgfutil@definecolor{PuOr-I}{RGB}{254,224,182} \pgfutil@definecolor{PuOr-H}{RGB}{247,247,247} \pgfutil@definecolor{PuOr-G}{RGB}{216,218,235} \pgfutil@definecolor{PuOr-F}{RGB}{178,171,210} \pgfutil@definecolor{PuOr-E}{RGB}{153,142,195} \pgfutil@definecolor{PuOr-D}{RGB}{128,115,172} \pgfutil@definecolor{PuOr-C}{RGB}{94,60,153} \pgfutil@definecolor{PuOr-B}{RGB}{84,39,136} \pgfutil@definecolor{PuOr-A}{RGB}{45,0,75}

You are absolutely right that the scheme name doesn't fit the order of colors in it. Good catch.

It seems that this "bug" already is present in the source on http://colorbrewer2.org. I have written Cynthia an email an we will see what should be the right order, i.e., if the name of the scheme is wrong or if the colors are given in the wrong order.

A hint that the colors are given in the wrong order can be found in e.g. https://www.census.gov/population/www/cen2000/atlas/pdf/censr01-103.pdf#page=2 where the scheme starts with a Purple color.

@ Stefan Pinnow I am unsure how to proceed right now, seems as if it is "need input from Cynthia". Or is it clear how to fix the issue?

Because Cynthia didn't answer up to now so I doubt she ever will. As I already stated I think the colors are already defined wrong on the website and are correct shown in the "Atlas". So my recommendation is to change the colors according to Markus' suggestion.

Unfortunately this would lead to an incompatible change. But seeing it as removing a "bug" is hopefully justifying that change. In addition when the feature request reverse colormaps would be implemented, some code already using this colormap could easily be adapted to work again.
