Here are some color schemes I've used for an extended period of time and like. I am keeping them here as a reference to share with others and make it easier for me to switch back in the future.
To get started, clone the repository to your machine and follow the steps for the color scheme you'd like to use.
$ git clone https://github.com/chrishunt/color-schemes.git
To test your color scheme:
$ ./script/test
