Highlighting a Letter with HTML: A Quick Tutorial

[topsquark]

Note: You'll have to quote this to see the code. I don't think the noparse tags are working here.

I recently wanted to correct a member's equation and wanted to highlight a change. I decided to change a letter's color to red:
[math]T \left ( \left [ \begin{array}{c}x-2y \\ 3x-y \end{array} \right ] \right ) [/math]

I'd like to highlight the T: T

But this gives:
[math]T \left ( \left [ \begin{array}{c}x-2y \\ 3x-y \end{array} \right ] \right ) [/math]How do I fix this?

Thanks!

$${\color{red}{T}}\left(\begin{bmatrix}
x-2y\\ 3x-y
\end{bmatrix}\right)$$

Like so?

YES! Thanks for the tip. For some reason I didn't think of changing the color in LaTeX code. (Doh)
