Belowtr.vim is a project mainly written in Vim Script, it's free.
A Vim color scheme
Based on the zmrok.vim color scheme by Krzysztof Goj, with elements from wombat256.vim by David Liang, wombat.vim by Lars Nielsen, and desert256.vim by Henry So Jr.
Somewhat reminiscient of the palette used in the game Below the Root.
