Change navigation bar background color

Hi,

I have desperately been trying to change the background color of the navigation bar of my website...

It should look like this: https://www.couldihavethat.com/

The logo should be in the top left corner with no background color.

Thanks everyone for your help

Can you share link to your site?

header background or navigation background?

nav.Header-nav.Header-nav--primary {
    background: blue;
}
