Text Formatting ⇒ Underbrace color

[pisoir]

Hello, is it possible to change the color of underbrace only? I have an equation that is in normal black color, and I underbrace some part of it. However, I want to have the underbrace in light gray color. Is is somehow possible to change the color only of the brace and not the text? Thank you.

You could just turn the color back to black inside the brace, e.g.:

Code: Select all

\documentclass{article}
\usepackage{xcolor}
\begin{document}
$\textcolor[gray]{0.8}{\underbrace{\textcolor{black}{this~is~black}}_{\textcolor{black}{this~too}}}$ 
\end{document}

Thank you. That's what I actually did it the meantime. Here is my macro:

\newcommand{\ubcolor}[2]{\color{#1}{\underbrace{\color{black}{#2}}}}

Thanks anyway.
