Incorrect color output inside of tables

[djn-ams]

When TeXML encounters a \color command inside of math mode, inside of a table cell, it outputs the color as RGB in the generated .css file. ams-html is expecting hex color codes.

Here's a MWE:

\documentclass{amsart}

\usepackage{xcolor}

\begin{document}

\begin{tabular}{cc}
{\color{red}$X$} & ${\color{blue}X}$
\end{tabular}

\end{document}

This produces the following .css:

.texml-c { color: #ff0000 }
.texml-pl { padding-left: 5.0pt }
.texml-pr { padding-right: 5.0pt }
.texml-tac { text-align: center }
.texml-c1 { color: [RGB]{0, 0, 255} }
.texml-bcc { border-collapse: collapse }

After thinking about this, I believe the problem is not that the wrong color space is being produced, but rather that TeXML is extracting this \color command to the CSS in the first place. For example, consider the following:

\documentclass{amsart}

\usepackage{xcolor}

\begin{document}

\begin{tabular}{c}
$X + {\color{red} Y}$ \\
Z
\end{tabular}

\end{document}

This produces the following CSS:

.texml-c { color: [RGB]{255, 0, 0} }
.texml-pl { padding-left: 5.0pt }
.texml-pr { padding-right: 5.0pt }
.texml-tac { text-align: center }
.texml-bcc { border-collapse: collapse }

and the following (relevant) XML:

  <table class="texml-bcc" id="tblrid1">
    <tr>
      <td class="texml-pl texml-pr texml-tac">
        <inline-formula content-type="math/tex">
          <tex-math class="texml-c">X + {Y}</tex-math>
        </inline-formula>
      </td>
    </tr>
    <tr>
      <td class="texml-pl texml-pr texml-tac">Z</td>
    </tr>

Note how the entire cell in the HTML now has the color attribute being applied to it, whereas in the TeX it's just the letter 'Y'. So it seems like the problem is that the relevant \color command is being extracted to the CSS rather than being passed along to MathJax.
