Nav & button colour change

[adm81]

Afternoon, 

I am trying to change the colour of the words in my nav bar but I think i need to do this in the CSS as no option in the builder. 

Also

There seems to be a colour which is used in a few places with the theme which I cant change in the builder. Button outline and a line at the bottom of each page. 

Would anyone know which line of the CSS i need to edit to chnage these colours.

For your navigation color, you're looking for this:

.wsite-menu-default a, .menu a {
    font-size: 14px;
    font-weight: bold;
    color: #bbbbbb;
}

And for the other color you mentioned, look for this:

.footer-wrap {
    border-top: 4px solid #5e8791;
    font-size: 13px;
    color: #cccccc;
}
