For the past couple of years I've been using Kuvva.com to do this: in addition to having a nice selection of wallpapers their Mac app also correctly keeps the wallpaper the same on all monitors/spaces.
But with this gem I can use my own desktop pictures and still have consistent images across virtual and physical screens!
I'm not certain about the exact color scheme, but my terminal looks pretty similar. I use a ZSH shell, and I use Oh My ZSH to manage my configuration. The ZSH theme I use is called "amuse", and it looks pretty similar to this one. Hope that helps!
