How to make a string in single quotes is highlighted as blue?

[quantonganh]

I would like to use single quotes for pillar.get or concatenate strings:

but also want to highlight the string as blue like in the second line.

How to do that?

My ~/.vimrc:

set backup
let day = strftime("%Y-%m-%d")
let user = substitute(system('whoami'), '\n', '', '')
if user == 'root'
    let backupdir = "/var/root/.vim/backup/".day
else
    let backupdir = $HOME."/.vim/backup/".day
endif
silent! let xyz = mkdir(backupdir, "p")
let cmd = "set backupdir=".backupdir
execute cmd
let time = strftime(".%H:%M:%S")
let cmd = "set backupext=".time
execute cmd

syntax on
set number
set background=dark
let g:solarized_termcolors = 256
let g:solarized_visibility = "high"
let g:solarized_contrast = "high"
let g:solarized_termtrans = 1

Good question! It's hard because if we colorize the jinja too much, it will be hard to distinguish from the YAML. But maybe that won't be much of an issue. I don't have anything against colorizing strings in jinja.
