MathJax Equation Coloring

 Expressions can be colored using the \color{} macro. For example \color{red}{R} + \color{green}{G} + \color{blue}{B} produces $\color{red}{R} + \color{green}{G} + \color{blue}{B}$ A more LATEX-compatible \color command can be obtained from the MathJax color extension. (See the MathJax Documentation for details.)
