" A colour scheme inspired by reflections at :
" https://jameshfisher.com/2014/05/11/your-syntax-highlighter-is-wrong/
"
" The accent and shade series are coming from Themer.
" Roughly, this sets :
"   - Normal slighlty muted
"   - Function and Statement clearly muted
"   - Comments as the only true foreground-colour text
"   - Constant in green - this applies to eg static strings
"   - Identifier, Character, Special and PreProc to cyan
"   - Type in magenta - kind of "special standout"
"   - Underlined in pink
"   - Todo in orange instead of red
"   - Error in red - the only one not changed
"
" TODO update fugitive and GitGraph* highlighting groups
"
