Clues was initially based on a Visual Studio theme called 'Blues 'n Roots' however it's a long way from looking much like it, aside from the occasional color accent, Blues (despite it's name) has a more toasted caramel flavor. Clues on the other hand is made up of cooling colors with a couple of flecks of light cream/brown/orange to break up any monotony, with yellow/gold rainbow-delimiters.

Clues has become my working theme of choice since about 7/20, and with xterm-frobs.el, looks really excellent in the terminal as well as the GUI.
