I want to combine two different tikzset. The first one is the default one. For instance

% Source: The PGF/TikZ manual

documentclass{standalone}



usepackage{tikz}

usetikzlibrary{mindmap,trees}

begin{document}

pagestyle{empty}

begin{tikzpicture}

  path[mindmap,concept color=black,text=white]

    node[concept] {Computer Science}

    [clockwise from=0]

    child[concept color=green!50!black] {

      node[concept] {practical}

      [clockwise from=90]

      child { node[concept] {algorithms} }

      child { node[concept] {data structures} }

      child { node[concept] {pro-gramming languages} }

      child { node[concept] {software engineer-ing} }

    }  

    child[concept color=blue] {

      node[concept] {applied}

      [clockwise from=-30]

      child { node[concept] {databases} }

      child { node[concept] {WWW} }

    }

    child[concept color=red] { node[concept] {technical} }

    child[concept color=orange] { node[concept] {theoretical} };

end{tikzpicture}end{document}

The second one is its variation found here How to draw only the border for the nodes in TikZ Mindmap?

documentclass{standalone}



usepackage{tikz}

usetikzlibrary{mindmap,trees}

tikzset{concept/.append style={fill={none}}}

begin{document}

pagestyle{empty}

begin{tikzpicture}

  path[mindmap,concept color=black,text=black]

    node[concept] {Computer Science}

    [clockwise from=0]

    child[concept color=green!50!black] {

      node[concept] {practical}

      [clockwise from=90]

      child { node[concept] {algorithms} }

      child { node[concept] {data structures} }

      child { node[concept] {pro-gramming languages} }

      child { node[concept] {software engineer-ing} }

    }  

    child[concept color=blue] {

      node[concept] {applied}

      [clockwise from=-30]

      child { node[concept] {databases} }

      child { node[concept] {WWW} }

    }

    child[concept color=red] { node[concept] {technical} }

    child[concept color=orange] { node[concept] {theoretical} };

end{tikzpicture}

end{document}

which just draws the border.

Say that I want to have a single document (for instance a beamer presentation; one slide with the mind map with colors, another slide with the mind map with just the border), how can I modify locally tikzset? Thanks a lot!

As suggested, you can use tikzpicture separately for each beamer slide.

The style is passed as an option to the tikzpicture.

Here is the code.

documentclass{beamer}



usepackage{tikz}

usetikzlibrary{mindmap,trees}

begin{document}

pagestyle{empty}

begin{frame}

begin{tikzpicture}[scale=0.7,transform shape]

  path[mindmap,concept color=black,text=white]

    node[concept] {Computer Science}

    [clockwise from=0]

    child[concept color=green!50!black] {

      node[concept] {practical}

      [clockwise from=90]

      child { node[concept] {algorithms} }

      child { node[concept] {data structures} }

      child { node[concept] {pro-gramming languages} }

      child { node[concept] {software engineer-ing} }

    }

    child[concept color=blue] {

      node[concept] {applied}

      [clockwise from=-30]

      child { node[concept] {databases} }

      child { node[concept] {WWW} }

    }

    child[concept color=red] { node[concept] {technical} }

    child[concept color=orange] { node[concept] {theoretical} };

end{tikzpicture}

end{frame}

begin{frame}

begin{tikzpicture}[concept/.append style={fill={none}},scale=0.7,transform shape]

  path[mindmap,concept color=black,text=black]

    node[concept] {Computer Science}

    [clockwise from=0]

    child[concept color=green!50!black] {

      node[concept] {practical}

      [clockwise from=90]

      child { node[concept] {algorithms} }

      child { node[concept] {data structures} }

      child { node[concept] {pro-gramming languages} }

      child { node[concept] {software engineer-ing} }

    }

    child[concept color=blue] {

      node[concept] {applied}

      [clockwise from=-30]

      child { node[concept] {databases} }

      child { node[concept] {WWW} }

    }

    child[concept color=red] { node[concept] {technical} }

    child[concept color=orange] { node[concept] {theoretical} };

end{tikzpicture}

end{frame}

end{document} 

The beamer slides would look like this:
