Default NSBox background color

Use Digital Color meter to find it (find it with Finder search); it is 227 for all 3 values, so 0.89

If I draw a border, the default fill color is the regular window background. To avoid gymnastics for dark mode, I was just wondering if there was a system color name for it.

I don't know of a system color name for it.

In https://developer.apple.com/documentation/uikit/uicolor

there are only 3 variations of gray

class var darkGray: UIColor

class var gray: UIColor

class var lightGray: UIColor

extension UIColor {
    public static let mildLightGray = UIColor(red: 0.8, green: 0.8, blue: 0.8, alpha: 1.0)
    public static let veryLightGray = UIColor(red: 227/255, green: 227/255,, blue: 227/255,, alpha: 1.0)
}

let backColor : UIColor = .veryLightGray

I am using Cocoa/Appkit/NSColor, but I was hoping to support dark mode by using system colors. NSColor's label colors were getting there, but at that rate I would need quinary or senary label colors.

Thanks

It is exactly the same for OSX. Just replace UIColor by NSColor …

What is the background color of NSBox in darkmode ?

It's always a good idea to read the AppKit Release Notes: https://developer.apple.com/documentation/appkit/appkit_release_notes_for_macos_10_14
