    UIGraphicsBeginImageContextWithOptions(rect.size, NO, [UIScreen mainScreen].scale);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSaveGState(context);

    [color setFill];
    CGContextFillRect(context, rect);

    CGContextSetBlendMode(context, kCGBlendModeNormal);
    [image drawInRect: rect blendMode:kCGBlendModeDestinationIn alpha:1];

    UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return img;
