Color in storyboard not matching UIColor

I had the same issue. I was seeing runtime RGB values of the colors from storyboards not matching UIColors created at runtime in code. I was able to fix this in storyboards by setting the color to be "Generic RGB" (vs the default of sRGB) when configuring it. Here is a screenshot of what I'm talking about in IB:

With code, UIColor init(red:green:blue:alpha:) method return color object with sRGB color space; With xib / StoryBoard, we need to select "sRGB IEC..." if we want to get same appearance as using code.

Such as:

UIColor.init(red: (20.0/255.0), green: (20.0/255.0), blue: (20.0/255.0), alpha: 1.0)

xib / StoryBoard screenshot

Actually，this problem has nothing to do with iOS 10. After iOS 10, UIColor init uses "extended sRGB" instead of sRGB. And this will causes problems only when we use r g b values below 0.0 and above 1.0.

I recently faced this problem and none of the posted answers did it. It turns out that with the release of iOS 10 SDK, the UIColor initializer init(red:green:blue:alpha:) now uses the extended sRGB range, so you have to set accordingly when configuring your color values on the Storyboard.

In my case what was exactly accurate was Color LCD:

I hope I've helped :-D
