I am defining a color in code as
[UIColor colorWithHue:32.0/360.0 saturation:0.88 brightness:0.97 alpha:1]
If I try to set the same color in storyboard, when running the App it is a slightly different colour to the one defined in code. If I drag the color to the palate then select a different color and select the palate one again, the HSB values are slightly different. It seems it is snapping to a different (RGB?) color in interface builder.
Xcode 8+, iOS 10+
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.
