If you try to get color from image through CGBitmapContextGetData and set, for example, in background of view, this will be different colors in iPhone 6 and later. In iPhone 5 everything will be ok) More information about this Getting the right colors in your iOS app

This solution through UIImage give you right color:

- (UIColor *)getColorFromImage:(UIImage *)image pixelPoint:(CGPoint)pixelPoint {

    CGImageRef imageRef = CGImageCreateWithImageInRect([image CGImage], CGRectMake(pixelPoint.x, pixelPoint.y, 1.f, 1.f));
    UIImage *croppedImage = [UIImage imageWithCGImage:imageRef];
    CGImageRelease(imageRef);

    return [UIColor colorWithPatternImage:croppedImage];

}
