N.2. Configuring the Colors
The actual colors to be used are configured using the environment variable
PG_COLORS
(note plural). The value is a colon-separated list of
pairs. The keys specify what the color is to be used for. The values are
SGR (Select Graphic Rendition) specifications, which are interpreted by the
terminal.
