Why my controls of Samsung Music app are white? Samsung S9 +

[Android Central Question]

Before the new update (Android Pie) my controls in the notification bar for Samsung Music used to be black, now the controls are white, making them dificult to see and to controll what song play.
I tried to see the setting but there is nothing about "Color of the controls".
