As I was calling the bottom sheet, I was calling the colors function like this

colors = NavigationBarItemDefaults.colors(
  indicatorColor = MaterialTheme.colorScheme.surface,
  selectedIconColor = MaterialTheme.colorScheme.onSurface,
  unselectedIconColor = MaterialTheme.colorScheme.onSurface,
),

but the latest material3 version is not providing sane defaults as it used to for the colors that I am not specifying explicitly. Instead I get black text on dark and light mode since I am not specifying a specific color for selectedTextColor and unselectedTextColor.

These lines here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/NavigationBar.kt;l=312-321?q=NavigationBarItemDefaults are the ones that probably break this behavior. Which was introduced here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/NavigationBar.kt;l=312-321?q=NavigationBarItemDefaults This Unspecified color is then used over here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/NavigationBar.kt;l=445-451?q=NavigationBarItemDefaults Interestingly, the deprecated method which says "Use overload with disabledIconColor and disabledTextColor", does seem to properly set some sane defaults for the parameters you may not be specifying.

In contrast, for NavRail this was not broken in the latest update, see here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/NavigationRail.kt;l=308-317?q=NavigationRailItemDefaults

I would expect here to get either a more sane default meaning something from the MaterialTheme which is more likely to have the right value for dark and light mode like it did before. This simply breaks the layout completely as the text is completely illegible by default.
