**		Version	:	1.2															 **
**		St_num	:	     														 **
**		History	:   have made this version more generalised and					 **
**					improved naming conventions. Still would like to improve the **
**					colour selection choice and should be improved next version  **
**					Added Orange to the color scheme( ugly)						 **
**					FIXED warnings when using light background colours			 **
**					I have not commented this file as it is only for screen		 **
**					manipulation and has is not part of the assignment 			 **
**					requirements												 **
