Color(UIColor.systemBackground)

In SwiftUI, you can use UIColor.systemBackground with Color(.systemBackground), but that doesn't work in SkipUI, where UIColor is just a basic data model with no built-in static colors.

In theory, you should be able to add a static (bridged) UIColor.systemBackground property, but I expect that the Compose version of obtaining the systemBackground property would require a @Composable function. But maybe there is a way to hold a symbolic reference to it, and then resolve it within any Composable that references it…
