Using color can significantly enhance the readability of mathematical equations in LaTeX. To apply color, use the \color command. For instance, \color{blue} x^2 renders as .

By default, the color will “leak” into subsequent parts of the equation. To limit the scope of a color, wrap the relevant part in curly braces. For example:

{\color{blue} x^2} + \color{red} y^2

This will display as , with the + symbol remaining uncolored.
