如何更改图像中红色的默认色调？

Question

在我的应用程序中，我需要更换一种颜色，我使用颜色选择器来做它。对于一件红色衬衫，我需要应用颜色，它不完全正常工作，并出现深色阴影。我们可以改变红色的色调与拾取器颜色兼容？这是我的代码

    imageLayer = [CALayer layer];
    NSLog(@"imageLayer %@",imageLayer);
    NSLog(@"self.layer %@",self.layer);
    imageLayer.frame = CGRectMake(0, 0, 660, 1000);
    imageLayer.cornerRadius = 10.0;
    imageLayer.backgroundColor = [UIColor clearColor].CGColor;
    //imageLayer.contents = (id) [UIImage imageNamed:@"3.png"].CGImage;
    imageLayer.masksToBounds = YES;
    [self.layer addSublayer:imageLayer];
    subLayer = [CALayer layer];
    subLayer.frame = CGRectMake(0, 0, 660, 1000);
    subLayer.cornerRadius = 10.0;
    subLayer.backgroundColor = [UIColor clearColor].CGColor;
    subLayer.contents = (id) [UIImage imageNamed:@"1.png"].CGImage;
    [imageLayer addSublayer:subLayer];
