What color is your terminal background?
If you're going to staring at a terminal emulator for any significant portion of your day, you had better make it pleasing to your eyes. As with any part of the Linux operating system (and most other open source Unix-like systems), the options for customizing for your viewing pleasure are seemingly endless. There are many sample palettes out there to get you started, with some like Solarized carrying with them a dedicated fanbase. Regardless of what you choose, we all might agree that once you have your terminal tweaked to perfection, using just about anything else seems painful.
So we ask you, dear reader, what does the background to your terminal look like?
