How to change logos in Black color by using bclogo.sty

Question

Is this possible to change \bclampe color to Black color? My tags are follows:

\documentclass{book}
\usepackage{environ} %fancy boxes
\usepackage{tikz}
\usetikzlibrary{patterns,shapes,arrows,calc,decorations.pathmorphing,backgrounds,graphs,positioning,fit,petri}
\tikzstyle{cuadricula}=[gray ,thick,dashed] %style for tike grids
\usetikzlibrary{decorations}
\usepackage{pgfplots} \pgfplotsset{compat=1.7}
\usepackage[tikz]{bclogo}

\NewEnviron{myidea}[1]
  {\par\medskip\noindent
  \begin{tikzpicture}
    \node[inner sep=0pt] (box) {\parbox[t]{.99\textwidth}{%
      \begin{minipage}{.3\textwidth}
      \centering\tikz[scale=5]\node[scale=2,rotate=30]{\bclampe};
      \end{minipage}%
      \begin{minipage}{.65\textwidth}
      \textbf{#1}\par\smallskip
      \BODY
      \end{minipage}\hfill}%
    };
    \draw[black,line width=3pt]
      ( $ (box.north east) + (-5pt,3pt) $ ) -- ( $ (box.north east) + (0,3pt) $ ) -- ( $ (box.south east) + (0,-3pt) $ ) -- + (-5pt,0);
    \draw[black,line width=3pt]
      ( $ (box.north west) + (5pt,3pt) $ ) -- ( $ (box.north west) + (0,3pt) $ ) -- ( $ (box.south west) + (0,-3pt) $ ) -- + (5pt,0);
  \end{tikzpicture}\par\medskip%
}

PS: I need to get all logos in Black color only...

Answer 1

The logos in bclogo are drawn with Metapost.

Find bc-lampe.mp on your system. Copy it to your working directory as bc-lampe-bw.mp.

Open the file and change

drawoptions (withcolor (1.000000,1.000000,0.000000));

into

drawoptions (withcolor (1.000000,1.000000,1.000000));

This is where yellow is used, changed into white.

Run Metapost on the file.

In your document, add

\newcommand{\bclampebw}{\includegraphics[width=\logowidth]{bc-lampe-bw}}

and in your code change \bclampe to \bclampebw.

This is the file bc-lampe-bw.mp (already with the change)

endfig;
end

As far as I can see, bclogo is released under LLPL 1.3, so changing a file is allowed (also changing the name, which is not required, but preferred).
