I’m developing an application in Kotlin. The text inside my ComboBox is not visible if I don’t assign a color, and it is also not visible in dark mode. Is there a simple solution for this without setting a color?

 @Composable // Composable function // Composable fonksiyon // UnitConverter function // UnitConverter fonksiyonu
    fun UnitConverter(name: String, modifier: Modifier = Modifier) {
      Column (
    modifier = modifier.fillMaxSize(), // Fill the entire screen (width and height) // Ekranın tamamını doldur (genişlik ve yükseklik)
          verticalArrangement = Arrangement.Center, // Center the content vertically,
          horizontalAlignment = Alignment.CenterHorizontally // Center the content horizontally // İçeriği yatay olarak ortalayın
    // İçeriği dikey olarak ortalayın
    
      )
        {
            Text("Unit Converter") // Text // Metin
            Spacer(modifier = Modifier.height(16.dp))
            OutlinedTextField(value = "", onValueChange = { // 
           OutlinedTextField // Dışbükey metin alanı
                /*TODO*/
    
            })
            Spacer(modifier = Modifier.height(16.dp))
            Row {
                Box {
                    Button(onClick = { /*TODO*/ }) {  // Button // Düğme
                        Text("Select")
                        Icon(Icons.Default.ArrowDropDown, contentDescription = "Arrow Down")
    
                    }
                    DropdownMenu(expanded =true, onDismissRequest = { /*TODO*/ }) {
                        DropdownMenuItem(text = { Text("Centimeters", color = Color.Black) }, onClick = { /*TODO*/ })
                        DropdownMenuItem(text = { Text("Meters", color = Color.Black) }, onClick = { /*TODO*/ })
                        DropdownMenuItem(text = { Text("Feet" , color = Color.Black) }, onClick = { /*TODO*/ })
                        DropdownMenuItem(text = { Text("MiliMeters", color = Color.Black) }, onClick = { /*TODO*/ })
    
                    }
    
                }
                Spacer(modifier = Modifier.height(16.dp))
                Box {
                    Button(onClick = { /*TODO*/ }) {
                        Text("Convert")
                        Icon(Icons.Default.ArrowDropDown, contentDescription = "Arrow Down")
    
                    }
    
    
                    DropdownMenu(expanded =true, onDismissRequest = { /*TODO*/ }) {
                        DropdownMenuItem(text = { "ss" }, onClick = { /*TODO*/ })
                        DropdownMenuItem(text = { Text("Meters", color = Color.Black) }, onClick = { /*TODO*/ })
                        DropdownMenuItem(text = { Text("Feet" , color = Color.Black) }, onClick = { /*TODO*/ })
                        DropdownMenuItem(text = { Text("MiliMeters", color = Color.Black) }, onClick = { /*TODO*/ })
    
                    }
    
                }
            }
            Spacer(modifier = Modifier.height(16.dp))
            Text("Result")
        }
    }

Text default color black
