It's not a collection per se, but the "same" color table as
some applications use by OR'ing the color pair into a chtype.

However, color_set takes a short for the pair number, while
the field in chtype is (for ncurses) only 8 bits).

The type is a short (signed) since that corresponds to the
type used for numbers in compiled terminfo.

(I see the manpage has a typo - it refers to the given window, which
would be for wcolor_set).
