PGFplots library SmithChart and Colorbrewer incompatible?

Question

What I want: Using Colorbrewer in a Smith Chart

What I have: I can use regular colors like red, green, and blue, but a specified colorbrewer scheme does not seem to work.

What I tried: I used the colorbrewer library before, so I have some working pictures with rectangular plots but for a smith chart it does not seem to work, or I might still have errors in my code.

an MWE:

\documentclass[margin=10pt]{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12} 
\usepgfplotslibrary{smithchart}
\usepgfplotslibrary{colorbrewer}
\pgfplotsset{cycle list/Set1}

\begin{document}
\begin{tikzpicture}[cycle list name=Set1,]
\begin{smithchart}[
%   cycle multi list={Set1-4}, % different (kinda desperate) approaches
    colormap name={Set1},
%   cycle list name=Set1, % my regular setting
]   
\draw[] (0,1) --(1,0);
\end{smithchart}
\end{tikzpicture}
\end{document}

edit: solved:

\documentclass[margin=10pt]{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}
\usepgfplotslibrary{smithchart}
\usepgfplotslibrary{colorbrewer}
\pgfplotsset{cycle list/Set1-4}
