How to change color copyright bar for only home page

Hi there,

you can use this CSS:

.home .site-info {
    background-color: #f00;
    color: #000;
}

Thanks you David, it's working.

so as you can see on my site my copyright bar is black on the home page and white on the rest of the site. the problem is that I have the copyright text in white. I would like to put it in black for all the site and leave it in white as is already the case on the home page

OK - in Customizer > Colors set the footer colors you require for ALL the other pages.
And then change your CSS to this to set the home page colors:

.home .site-info {
    background-color: #454040;
    color: #fff;
}

Thanks You David it's working.

Glad to hear that!
