Alternately, if you import C<:constants>, you can use the constants CLEAR,
RESET, BOLD, DARK, UNDERLINE, UNDERSCORE, BLINK, REVERSE, CONCEALED, BLACK,
-RED, GREEN, YELLOW, BLUE, MAGENTA, ON_BLACK, ON_RED, ON_GREEN, ON_YELLOW,
-ON_BLUE, ON_MAGENTA, ON_CYAN, and ON_WHITE directly. These are the same as
-color('attribute') and can be used if you prefer typing:
+RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, ON_BLACK, ON_RED, ON_GREEN,
