Now that ncurses 6.0 has been released, it supports 64-bit processors and 256+colors. Python 3.6.1 should have been updated to support the new ncurses 64-bit API. It does not seem to have been updated. With the ncurses5.x 32-bit API, the Python 2x and 3x curses modules supported up to 16 colors and up to 64 color pairs. The updated curses packages should support at least 256 colors and at least 65536 color pairs.

I neglected to state that ncurses 6.0 changed certain c/c++ data types to support the additional data bits needed to support more colors. The Python curses stdlib needs to reflect the new c/c++ ncurses data types.
