Using Color Commands for Math Operators

Question

I was wanting to know how is it possible to create a math symbol in color to position correctly. I have used the following but the top limit does not center properly. Sorry for the verbage as I don't know how to word the question precise and clearly. Here is a mwe of the problem:

\documentclass[11pt]{article}
\usepackage{color}

\begin{document}

\[ \sum_{\color{red} m=0}^{\color{red}{\infty}}  \]

\end{document}

Which produces the following below:

Answer 1

Use \textcolor instead, such as

\[ \sum_{\textcolor{red}{m=0}}^{\textcolor{red}{\infty}}  \]

\color is a switch / declaration, it requires grouping to limit its effect such as by additional curly braces. \textcolor affects just its argument and works for math as well.
