Jetpack Compose:文本字段颜色被忽略且不应用

我正在尝试设置/删除文本字段中的颜色,但未应用更改。我想通过设置透明颜色和改变光标颜色来完全移除指示器。文本的颜色似乎很有效。

为什么不应用它以及如何使其工作?

代码:

Column(
    modifier = Modifier
        .fillMaxWidth()
        .border(1.dp, colorResource(id = R.color.dark_smoke), RoundedCornerShape(8.dp))
        .background(colorResource(id = R.color.white_smoke))
) {
    TextField(
        value = email.value,
        onValueChange = {
            email.value = it
            loginViewModel.verifyEmail(it.text)
        },
        colors = TextFieldDefaults.textFieldColors(
            cursorColor = colorResource(id = R.color.steel_blue),
            textColor = Color.DarkGray,
            backgroundColor = Color.Transparent,
            focusedIndicatorColor = Color.Transparent,
            unfocusedIndicatorColor = Color.Transparent,
            disabledIndicatorColor = Color.Transparent
        ),
        modifier = Modifier.fillMaxWidth(),
        isError = viewState.isEmailValid.not(),
        label = {
            Text(
                text = stringResource(R.string.username_hint)
            )
        },
        keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Email),
    )
}
