Fixed by change to the following:
-(id)initWithColor:(UIColor *)color {
if ((self = [super init])) {
// Need to deal with CTForegroundColor = "<CGColor 0x6d9de00> [<CGColorSpace 0x6d81eb0> (kCGColorSpaceDeviceGray)](0 1)";
if ([color getRed:&_red green:&_green blue:&_blue alpha:&_alpha] == NO) {
CGFloat white;
if ([color getWhite:&white alpha:&_alpha]) {
_blue = _green = _red = white;
// NSLog(@"Grayscale converted to Color");
}
};
}
return self;
}
