XF 2.2 How can I change the login button and registration button color?

[Luke247]

The two buttons in the nav bar... I want the login button to be a specific blue and the registration button orange. Will somebody please tell me how to achieve this?

You can try this

.p-navgroup-link--logIn {
    background: blue;
    color: white;
}
.p-navgroup-link--register {
    background: orange;
    color: black;
}

Change colour as you want.
