Description:
cream/brown/orange color theme for Emacs
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 its 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.
