       colortest-python - Display color test chart and convert between color




       Displays 256, 88 and 16 color tables depending on what the terminal
       supports. Also provides for conversion between 256 and 88 color values.

       The program automatically detects 8, 16, 88, 256 color capabilities
       (via ncurses) and displays the appropriate color charts. Program can
       display the colors as blocks or 2d cubes optionally with color values
       overlaid in int or hex values, it can show the full rgb text string and
       show the display with a vertical (default) or horizontal orientation.

       In addition to the color charts it can also convert between 256 and 88
       color values. This can be useful when converting various terminals like
       between urxvt and xterm-256.

       The goal of this program was to provide the functionality of all the
       various Perl and sh scripts in one place with some bells and whistles.
