I’m a chronic theme-fiddler, and I thought I’d try to use a version of the zenburn colour theme that I use in emacs and vim. It’s designed to be low-contrast, and easy on the eyes for extended use. Zenburn works well for me in Org mode (see here), so I thought I’d give it a go. If light-on-dark bothers you, or anything else come to that, let me know in the comments.
The WordPress theme is Parabola from cryout, which is fantastically customizable. The colour choices from the zenburn palette are my own.
