" Description: 16color scheme for vim
" Author: Timm Stelzer <timmstelzer@gmail.com>
" Source: https://github.com/tstelzer/welpe.vim
" ------------------------------------------------------------------------------

" ------------------------------------------------------------------------------
" How this works:
"
" Every call to the highlight command is wrapped in the `s:H` function.
" The function is called like this:
"
" call s:H(<Group>, <foreground>, <background>, <style>, <special>)
"
"   <Group> is a String, like "Normal". See `:help 'highlight-groups'`.
"
"   <foreground> and <background> are names of the welpe palette, like s:bg.
"     Avoid using direct reference to library colors which start with an
"     underscore, like s:_darkred; instead bind those to one of the 16 palette
"     colors.
"
"   <style> is one of 'italic', 'bold', 'underline' or 'undercurl'
"     Note that 'undercurl' is only available in the GUI, and the other three
"     depend on your choice of font, and your terminal settings.
"
"   <special> is the color of 'underline' or 'undercurl' and works only in the
"     GUI
"
" To allow an identical experience between terminal and GUI, this colors
" scheme limits itself to using exclusively colors from the 256-term palette.
" For reference, this color chart may be of help:
" http://www.calmar.ws/vim/256-xterm-24bit-rgb-color-chart.html
"
" Remembering each of those by hex is silly, so sounding names have been made
" up, roughly following existing palettes. Hex-values and the corresponding
" 256-term-values, and additionally 16- and 8-term-values for future
" reference, are locally available. See Library-section.
"
" Note: If you want to change assignments, change the palette by swapping the
" bound colors with existing colors from the library, or add new colors.
"
" For example, to use Venetian Red (#d70000) as a lightred, change the line
"
"   let s:lightred = s:_roman
"
" to
"
"   let s:lightred = s:_venetian
"
" Refrain from using library colors directly, to keep the layers separate and
" sane.
