When xcolor is loaded with the monochrome option, colour is disable for only some, but not all tikz operations.

  • Why is this?
  • Is it possible to disable colour for all operations?
  • is it possible not to disable colour for any operations?


(Without the monochrome option, everything is drawn in red.)


\textcolor{red}{Red}% black

\begin{tikzpicture}[node distance=1pt]
  \node (a) [text=red] {Red};% red
  \node (b) [fill=red,below=of a] {};% red
  \node (c) [draw=red,below=of b] {};% red
  \node (d) [above=of a] {\textcolor{red}{Red}};% black
  \draw [red] circle (1);% black
  \path [draw=red] circle (1.2);% red
