This is the closest I could get to this when I was using Mercurial daily. Using the color extension:

  [color]
  custom.rev = red
  custom.bm = yellow
  custom.date = green
  custom.author = blue

  [alias]
  lg = log -G --template "{label('custom.rev',node|short)} - {if(bookmarks,'(')}{label('custom.bm',bookmarks)}{if(bookmarks,') ')}{desc|firstline} ({label('custom.date',date|age)}) <{label('custom.author',author|person)}>" -b .
