tikzmath: strange replacement

Question

I don't know why, but I tried to print some code in a tikzmath file, and the result is really strange, it looks like that tikzmath tries to substitute texts even if does not begin with a backslash... For example here the variable is not even used, and a substitution is done...

MWE:

\documentclass{report}
\usepackage{tikz}
\usetikzlibrary{math}

\begin{document}

\begin{tikzpicture}
  \tikzmath{
    % Fails
    \color = "blue!80";
    % Works
    % \ccolor = "blue!80";
    {\draw[-latex] (0,0) -- (1,1) node{$\textcolor{red}{A}$};};
  }      
\end{tikzpicture}

\end{document}

Output:

Thank you!

Answer 1

The reason is that your statement \color = "blue!80"; overrides the TeX command \color. If you comment out this line, it also works as expected. Otherwise you can use {\draw[-latex] (0,0) -- (1,1) node[red]{$A$};};, but I'd recommend not to (ab)use TeX commands like this.
