+" This is a copy of the dark.vim theme, however it does not change colors in
+" the different modes, so should bring some performance improvements because
+" airline does not have to redefine highlighting groups after they have been
+" setup once.
+
+" Each theme is contained in its own file and declares variables scoped to the
+" file.  These variables represent the possible "modes" that airline can
+" detect.  The mode is the return value of mode(), which gets converted to a
+" readable string.  The following is a list currently supported modes: normal,
+" insert, replace, visual, and inactive.
+"
+" Each mode can also have overrides.  These are small changes to the mode that
+" don't require a completely different look.  "modified" and "paste" are two
+" such supported overrides.  These are simply suffixed to the major mode,
+" separated by an underscore.  For example, "normal_modified" would be normal
+" mode where the current buffer is modified.
+"
+" The theming algorithm is a 2-pass system where the mode will draw over all
+" parts of the statusline, and then the override is applied after.  This means
+" it is possible to specify a subset of the theme in overrides, as it will
+" simply overwrite the previous colors.  If you want simultaneous overrides,
+" then they will need to change different parts of the statusline so they do
+" not conflict with each other.
+"
+" First, let's define an empty dictionary and assign it to the "palette"
+" variable. The # is a separator that maps with the directory structure. If
+" you get this wrong, Vim will complain loudly.
+let g:airline#themes#dark_minimal#palette = {}
+
+" First let's define some arrays. The s: is just a VimL thing for scoping the
+" variables to the current script. Without this, these variables would be
+" declared globally. Now let's declare some colors for normal mode and add it
+" to the dictionary.  The array is in the format:
+" [ guifg, guibg, ctermfg, ctermbg, opts ]. See "help attr-list" for valid
+" values for the "opt" value.
+let s:N1   = [ '#00005f' , '#dfff00' , 17  , 190 ]
+let s:N2   = [ '#ffffff' , '#444444' , 255 , 238 ]
+let s:N3   = [ '#9cffd3' , '#202020' , 85  , 234 ]
+let g:airline#themes#dark_minimal#palette.normal = airline#themes#generate_color_map(s:N1, s:N2, s:N3)
+
+" Accents are used to give parts within a section a slightly different look or
+" color. Here we are defining a "red" accent, which is used by the 'readonly'
+" part by default. Only the foreground colors are specified, so the background
+" colors are automatically extracted from the underlying section colors. What
+" this means is that regardless of which section the part is defined in, it
+" will be red instead of the section's foreground color. You can also have
+" multiple parts with accents within a section.
+let g:airline#themes#dark_minimal#palette.accents = {
+      \ 'red': [ '#ff0000' , '' , 160 , ''  ]
