use CancelColor in mathjax

Question

I want to use \cancel{·} in mathjax. with a crossed line of different color, explained here.

I use

\[
enter code here
\require{xcolor}
\require{cancel}
\renewcommand\CancelColor{\color{red}}

\cancel{x^2}
\]

But is not working. Any ideas?

You could use

\newcommand\ccancel[2][black]{\color{#1}{\cancel{\color{black}{#2}}}}

so that

\ccancel[red]{x}

would use a red slash through a black x.

I still find appalling that MathJax uses \color as a substitute for \textcolor. It should be changed. Maybe too late, but if you want to imagine interchangeable code for MathJax and LaTeX, this is a stopping. – egreg Mar 01 '18 at 14:24
I am not aware of \textcolor, but the interchangeability is not important this time. Brilliant – manolius Mar 01 '18 at 15:42
@egreg, the MathJax color extension gets you a more LaTeX-compatible version of \color that includes \textcolor and several other macros, and makes \color act like a switch rather than taking an argument for what to color. You can include it in a MathJax configuration if you are managing your own page, or use \require{color} to load it if not. There is unfortunate history (and ignorance on my part) behind this use of \color. – Davide Cervone Mar 01 '18 at 18:15
