View source code for builtin emacs package

How can I view source code for a builtin Emacs package? For instance given lisp code (require 'color), I would be interested in which functions are provided by that package. I googled emacs "color.el" and found the source code. But I wonder if this file can be viewed directly from within Emacs itself? By the way, find . -name 'color*' gives

./share/emacs/24.3/lisp/color.el.gz
./share/emacs/24.3/lisp/color.elc

You can get to the source code in a single command with M-x find-library.

You can either open the file directly in Emacs. I think .gz files are by default decompressed. Usually, I pick out one function from the package I'm interested in (e.g. org-mode), look up the documentation for that using C-hf org-mode RET and then click on the file name in the documentation buffer. It will take you the source file.

So ./share/emacs/24.3/lisp/color.el.gz is the gzipped source code, and you can open that in emacs by first doing M-x auto-compression-mode, and then visiting that file.
