It could work.
In my small framework I use version blocks and I use ansi escape 
sequences for posix and SetConsoleTextAttribute for windoze.

Ofcourse there would be a need to create unified enumeration with 
colors as they differ on those platforms too.


                 public enum Font
		{
			Normal = 0,
			Underline = 0x8000,
			Reverse   = 0x4000,
		}
		
		public enum Color
		{
			Default = 0x0000,
			Blue  = 0x0001,
			Green = 0x0002,
			Aqua  = 0x0003,
			Red   = 0x0004,
			Purple= 0x0005,
			Yellow= 0x0006,
			Gray  = 0x0008,
			LightBlue  = 0x0009,
			LightGreen = 0x000A,
			LightAqua  = 0x000B,
			LightRed   = 0x000C,
			LightPurple= 0x000D,
		}

Those are colors and font-attributes that I found to match both 
Windows and Posix
