PCBoard defines some macros to change color if user has ANSI capabilities.

If user doesn't support ANSI, PCB just skip those codes. It is a good way to colorize your screens and prompt because you don't have to check the ANSI flag, PCB deal with it automatically.

Color codes are made of 4 bytes. the first byte is used to enter in macro mode. The second indicates that we want to pass a color code. Next byte is the background color and the last is the foreground color.
