My setBackgroundColor is Always Different from photoshop

My designers asks me to show a UIView with a Photoshop’s RGB of 125, 178, 60. So I set the color as in the code below:

+ (UIColor *) okThronColor {

    return [UIColor colorWithRed:(CGFloat)(125.0/255.0)
                           green:(CGFloat)(178.0/255.0)
                            blue:(CGFloat)(60.0/255.0) 
                           alpha:1];

}

Photoshop says me that the color is:

but the color on iphone is:

the problem cames with ALL the colors, every time. Why?

    I believe this comes down to colour profiles. If you are using Photoshop, if I remember correctly this is defaulted to a colour profile that is best suited to photo’s. Most dynamic range etc. Whereas the system will use as low a colour profile as possible because it is less of a memory footprint.

    This article here, suggests some methods to get around it to get the correct RGB values for iOS, with a bit more of an insight into why this is probably happening.

    In iOS 7 (and above) the navigation bar is translucent, and the color is affected by whatever lays behind it.

    Try setting the translucent property to NO.

    See the UINavigationBar documentation.
