Making it work with guicolorscheme Edit
This will allow you to use the theme in the terminal (not only in GUI mode).
Change all named colors (White, Yellow, ...) to their #RRGGBB variant, then install guicolorscheme.vim and add this to your vimrc:
runtime! plugin/guicolorscheme.vim GuiColorScheme blackboard
