I have no idea how to use a defined color in my ui with Curses.
To define a color, I need an instance of Curses :: UI :: Color ([As you can see here](https://github.com/Saul-BT/perl-playground/blob/32c08a9988a7ba344251c548bb6103c8b85c61e4/tetris/main.pl#L4)).
After defining the color 'purple', I don't know what I should do to use it in my UI.
