I am pretty new to Kotlin. I have a BottomNavigation wrapped in a Scaffold. The tabs background color change works well. But, though the icons are actually white, it appears black on the app, though I set the selectedContentColor to Color.White.

And unselectedContentColor to Color.White.copy(alpha = 0.7f).

It does not even show whether or not I am in one tab or the other. They all just remain the same.

This is the code for the Scaffold:

    Scaffold(
        bottomBar = {
            BottomNavigation(
                backgroundColor = Color(0xff6c247c),
                contentColor = Color.White
            ) {
                tabs.forEachIndexed { index, title ->
                    BottomNavigationItem(
                        icon = { Icon(painter = icons[index], contentDescription = title) },
                        label = { Text(title) },
                        selected = selectedTab == index,
                        onClick = { selectedTab = index },
                        alwaysShowLabel = true,
                        selectedContentColor = Color.White,
                        unselectedContentColor = Color.White.copy(alpha = 0.7f)
                    )
                }
            }
        }
    )

And my theme.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools">

    <style name="Theme.HSMApp" parent="android:Theme.Material.Light.NoActionBar" >
        <item name="colorPrimary">@color/primaryColor</item>
        <item name="colorPrimaryVariant">@color/primaryVariantColor</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/secondaryColor</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
    </style>

</resources>

I also have this is in my Theme.kt

    darkTheme: Boolean = isSystemInDarkTheme(),
    // Dynamic color is available on Android 12+
    dynamicColor: Boolean = true,
    content: @Composable () -> Unit
) {
    val colorScheme = when {
        dynamicColor && Build.VERSION.SDK_INT >= Build.VERSION_CODES.S -> {
            val context = LocalContext.current
            if (darkTheme) dynamicDarkColorScheme(context) else dynamicLightColorScheme(context)
        }

        darkTheme -> DarkColorScheme
        else -> LightColorScheme
    }
    val view = LocalView.current
    if (!view.isInEditMode) {
        SideEffect {
            val window = (view.context as Activity).window
            window.statusBarColor = colorScheme.primary.toArgb()
            WindowCompat.getInsetsController(window, view).isAppearanceLightStatusBars = darkTheme
        }
    }

    MaterialTheme(
        colorScheme = colorScheme,
        typography = Typography,
        content = content
    )
}

What should I change?
