Here's a more comfortable color scheme
The color scheme default in use on the website is, let's be honest, kind of painful. I wasn't able to handle it, so I coded up something I think is better. If you have Stylus installed, you can test it from : https://userstyles.org/styles/177564/kindle-like-color-scheme
It's CC0-licensed, so if the admins here would like to make use of it, they can. Rather, please do.
The userstyle patch is terrible fragile, unfortunately. Those class names look auto-generated and are likely to change. It works now at least.
