Can't change color on the notification bar

[Luis34]

Hi there. I can't change the notification bar on my S8 even when I change the theme. IS THIS NORMAL? ?

DEPENDS ON THE THEME! WHAT THEME ARE YOU USING!!??

Now I'm using the normal theme, but it still doesn't show the normal color on the notification bar. I tried changing the themes but it still doesn't change it. It's always the same color purple.
