 passes large sets of data through a pager. There are various way to
 change the colors.
 
 We can distinguish the coloration into 2 main categories:
 
-- The one that affect only the terminal client.
-- The ones that also affect client connected through the Jupyter

 governed by a ``colors`` attribute or configuration option that can
 take one of 3 case insensitive values: ``NoColors``, ``Linux`` and
 ``LightBG``.

+Colors that affect only the terminal client are governed mainly by
 ``TerminalInteractiveShell.highlight_style`` taking the name of a
 ``Pygments`` style.
 
 As of IPython 5.0 the color configuration works as follows:
 
   - by default, ``TerminalInteractiveShell.highlight_style`` is set to
-    ``legacy`` which **try to** emulate the colors of IPython pre 5.0,
