Never heard of zsh-syntax-highlighting before, pretty cool feature! Apparently it's in zprezto, if you want to enable it, just add

      'syntax-highlighting' \

to your .zpreztorc (below "zstyle ':prezto:load' pmodule \" line)

and uncomment

    zstyle ':prezto:module:syntax-highlighting' highlighters \
      'main' \
      'brackets' \
      'pattern' \
      'cursor' \
      'root'
