Changing text colour for primary menu (in the masthead)

Hi.
Is there a simple css snippet to change the main (not rollover) text colour of the primary navigation menu ?
Cheers

I have tried this (below) but then the rollover colour change stops working.

@media only screen and (min-width: 1025px) {
  .main-navigation ul.menu > li > a {
    color: #000;
  }
}

Hello, try to replace this additional CSS code:

@media (min-width: 1025px) {
    #masthead:not(.header-scrolled) {
        background-color: white;
    }
}

…with this:

@media (min-width: 1025px) {
    #masthead:not(.header-scrolled) {
        background-color: white;
        transition-duration: 0.5s;
    }

    .site-title a,
    .site-description,
    .main-navigation a{
        color: black
    }
}

Kind Regards, Roman.
