Xcode nav background color

Hi I am new just installed the latest xcode last week.

want to set xcode background colors like the ones in this video Build User Interfaces with SwiftUI - Lesson 3 (How To Make An App) - YouTube.

tried Preference/theme, but no options to set burgundy color for nav section. Please help. thanks! - Ben

This isn’t really possible it’s burgundy because Chris’ background is red and Xcode is opaque letting some of the color through, I believe this is a feature of Xcode 11
