+  " 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.
