Can the colour of these text be changed?

[Guest 1319987654321]

I borrow this pic

I wanna change the colour of this screen (this screen is shown when someone is calling you , i dont know what that's called)

I change every item in colour scheme but no luck

Thanks for your help

I believe the top bit is always black no matter what :) But I think you can change the white text
