How to set emacs theme?

Question

I am new to emacs and wondering how I would get it to load a theme of my choosing (http://lambda.nirv.net/m/files/color-theme-chocolate-rain.el)

I am on ubuntu, and have no idea what I am doing (yet :P) in regards to Emacs, for the most part.

Answer 1

Here you go: http://www.nongnu.org/color-theme/.

Answer 2

This should work (you probably need to change color-theme-tty-dark to color-theme-chocolate-rain:

;; Enable a color theme
(require 'color-theme)
(color-theme-initialize)
(color-theme-tty-dark)
