That's the difference between providing something for extensive reuse  
and something that fulfils specific needs in my app ;-)
Usually, the latter evolves slowly to the first, with the pressure on  
slowly, that's why it's done that way yet, at least the "proper" idea  
is there ;-)

The color you can replace to your liking, here's the relevant string  
method:

-(NSString *)filterDNABases
{
	int i;
     NSMutableString* filteredstring = [NSMutableString  
stringWithCapacity: [self length]];
	NSString *upper = [self uppercaseString];
	
	for(i=0; i<[upper length]; i++){
		
		switch([upper characterAtIndex: i]){
			case 'A':
				[filteredstring appendString: @"A"];
				break;
			case 'C':
				[filteredstring appendString: @"C"];
				break;
			case 'G':
				[filteredstring appendString: @"G"];
				break;
			case 'T':
				[filteredstring appendString: @"T"];
				break;
			case 'U':
				[filteredstring appendString: @"T"];
				break;
				
			case 'W':
				[filteredstring appendString: @"N"];	
				break;			
			case 'S':
				[filteredstring appendString: @"N"];	
				break;
			case 'M':
				[filteredstring appendString: @"N"];	
				break;			
			case 'K':
				[filteredstring appendString: @"N"];	
				break;
			case 'R':
				[filteredstring appendString: @"N"];	
				break;			
			case 'Y':
				[filteredstring appendString: @"N"];	
				break;
				
			case 'H':
				[filteredstring appendString: @"N"];	
				break;			
			case 'V':
				[filteredstring appendString: @"N"];	
				break;
			case 'D':
				[filteredstring appendString: @"N"];	
				break;			
			case 'B':
				[filteredstring appendString: @"N"];	
				break;
				
			case 'N':
				[filteredstring appendString: @"N"];	
				break;		
			
			default:
				break;
			}
     }
     return filteredstring;
}
