rainbow-delimiters.el:

Rainbow-delimiters is a "rainbow parentheses"-like Emacs mode for coloring parentheses, brackets, and braces according to their nested depth. It gives a visual reference for which delimiters match, and what statements are at the same depth - if several statements are at the same level, they will be the same color.

This is the official github repository for rainbow-delimiters. It is made available so people can easily contribute to the mode.
