" Set Color Variables: {{{
fun! s:set_color_variables()
" Helper: {{{
" -------
" Function to dynamically generate variables that store the color strings
" for setting highlighting. Each color name will have 2 variables with prefix
" s:fg_ and s:bg_. For example:
" if a:color_name is 'Normal' and a:color_value is ['#000000', '0', 'Black'],
" the following 2 variables will be created:
" s:fg_Normal that stores the string ' guifg=#000000 '
" s:bg_Normal that stores the string ' guibg=#000000 '
" Depending on the color mode, ctermfg and ctermbg will be either 0 or Black
"
" Rationale:
" The whole purpose is for speed. We generate these ahead of time so that we
" don't have to do look up or do any if-branch when we set the highlightings.
"
" Furthermore, multiple function definitions for each mode actually reduces
" the need for multiple if-branches inside a single function. This is not
" pretty, but Vim Script is slow, so reducing if-branches in function that is
" often called helps speeding things up quite a bit. Think of this like macro.
"
" If you are familiar with the old code base (v0.9 and ealier), this way of
" generate variables dramatically reduces the loading speed.
" None of previous optimization tricks gets anywhere near this.

" Color value format: Array [<GUI COLOR/HEX >, <256-Base>, <16-Base>]
" 16-Base is terminal's native color palette that can be alternated through
