I like vim's built-in desert colorscheme, but I wanted more colour.
Screenshot font is ProggyClean: set guifont=ProggyCleanTT:h11:cANSI:qDRAFT
Sandydune is a fork of desert that offers:
- gentle differentiation between different types (float vs int vs string)
- control statement colouring influenced by codekana
- diff and patch colours inspired by jellybeans
- some ugly red/brown colours replaced with blues
