Re: How to use color in equations when converting to MS Word ?

[John MacFarlane <jgm-TVLZxgkOlNX2fBVCVOL8/A@public.gmane.org>]

No, the warning is actually emitted by the writer.
The parser just stores the raw tex math; it gets
converted to the target format by the writer.

The filter would be quite easy, something like

function Math(el)
    el.text = el.text:gsub("\\color{%w+}", "")
    return el
end
