I added a UIButton to my view. It's a regular button of system type, default config and plain title, all default values. I set the text color property in IB to the RGB values shown below: r68, g66, b62

I made a custom color programmatically with the same RGB values:

extension UIColor {

    class var customColor: UIColor {
        return UIColor(red: 68/255, green: 66/255, blue: 62/255, alpha: 1)
    }
}

Why are the button's RGB values different when I check them in my view controller than what I set them to be in IB (identical to my custom color RGB values)?

// UIExtendedSRGBColorSpace 0.33669 0.327454 0.310221 1
myButton.titleColor(for: .normal)!.description)

// UIExtendedSRGBColorSpace 0.266667 0.258824 0.243137 1
UIColor.customColor.description

Shouldn't they be the same? If not, how do I get them to be the same?

It's the color space setting that does that. Look here: http://stackoverflow.com/questions/12686141/wrong-color-in-interface-builders-color-picker – Lefteris Jan 26 '17 at 20:15
I tried changing the color profile to both "Apple RGB" and "Generic RGB" and the values were still off. – Aaron Jan 26 '17 at 20:25
Do they LOOK the same when run? – Will Boland Jan 26 '17 at 21:09
Yeah they do look the same! – Aaron Jan 26 '17 at 21:44
Please try to set your buttons title colour as: myButton.setTitleColor(UIColor.customColor, forState: .Normal) – Mehul Sojitra Jan 27 '17 at 05:39
I'm surprised it works at all - I'd expect the button text to be black, since 68/255 and the others all evaluate to zero (integer division). – Extragorey Aug 15 '17 at 03:53
