    --
    -- |   curses support color attributes  on  terminals  with  that
    --     capability.   To  use  these  routines start_color must be
    --     called, usually right after initscr.   Colors  are  always
    --     used  in pairs (referred to as color-pairs).  A color-pair
    --     consists of a foreground  color  (for  characters)  and  a
    --     background color (for the blank field on which the charac-
    --     ters are displayed).  A programmer  initializes  a  color-
    --     pair  with  the routine init_pair.  After it has been ini-
    --     tialized, COLOR_PAIR(n), a macro  defined  in  <curses.h>,
    --     can be used as a new video attribute.
    --
    --     If  a  terminal  is capable of redefining colors, the pro-
    --     grammer can use the routine init_color to change the defi-
    --     nition   of   a   color.
    --
    --     The init_pair routine changes the definition of  a  color-
    --     pair.   It takes three arguments: the number of the color-
    --     pair to be changed, the foreground color number,  and  the
    --     background color number.  For portable applications:
    --
    --     -    The value of the first argument must be between 1 and
    --          COLOR_PAIRS-1.
    --
    --     -    The value of the second and third arguments  must  be
    --          between  0  and  COLORS (the 0 color pair is wired to
    --          white on black and cannot be changed).
