October (dark)
Octopress (Light)
Github
The default color for Octopress is not so good, how to change the color of the code block on Github-like?
I had the same problem, but I wanted the Twilight color scheme in my posts.
You can use kramdown and CodeRay instead of rdiscount, which allows you to choose the color associated with each code object in your snippets. I wrote a blog post on how to do this:

EDIT:
I found the GitHub theme for coderay here .
