Label color of disabled SwiftUI buttons

Question

What are the label colors of these disabled SwiftUI buttons? I would like to use the colors in my own button styles so that they are consistent with the existing styles.

I found that they have some transparency. Also, they are different in light and dark mode. But none of the system colors seems to match. I experimented with transparency, too, without success so far.

import SwiftUI

struct ButtonTestView: View {
    var body: some View {
        VStack(alignment: .leading) {
            Button("Button", action: {})
                .disabled(true)
            Button("Button (same BG as bordered)", action: {})
                .disabled(true)
                .background(Color(.secondarySystemFill))
            Button("BorderedButton", action: {})
                .buttonStyle(.bordered)
                .disabled(true)
            // Same with different background
            VStack(alignment: .leading) {
                Button("Button", action: {})
                    .disabled(true)
                Button("Button (same BG as bordered)", action: {})
                    .disabled(true)
                    .background(Color(.secondarySystemFill))
                Button("BorderedButton", action: {})
                    .buttonStyle(.bordered)
                    .disabled(true)
            }.background(Color(.label))
            Spacer()
        }.padding()
    }
}

Personally, I use.opacity(isDisable? 0.5: 1) on my button or stack to present disabled buttons. It will give you the disabled effect look and the transparent look too.
