 ## Credits
 The schemes Novel, Espresso, Grass, Homebrew, Ocean, Pro, Man Page, Red Sands, and Terminal Basic are ports of the schemes of the same name included with the Mac Terminal application. All of Terminal's schemes have now been ported, with the excption of "Solid Colors" (random backgrounds, which iTerm doesn't support) and "Aerogel" (which is hideous).

 The scheme Solarized Darcula was inspired by the color theme created by [@rickhanlonii](https://github.com/rickhanlonii). There are two screenshots below; one with a background and one without. The background image is included in the backgrounds/ directory and the image must be manually set on the profile's Preferences->Window tab. It's hard to see from the screenshot, but it looks great!
