Impossible to change footer and footnav color

cucina-it

I tried to change the default color of footer and footnav through the settings in the template options and it's showing the correct color in the preview

But on the production site the background color is still blue.
So I tried to change it in the custom.css file, adding the following code:

.t4-footnav .t4-module .ja-footnav {
background:#333333;
}
    
.t4-footer .ja-footer {
background:#000000;
}

But the background in the online site is still blue? How in the world can I change it to dark grey?

Thanks

.t4-palette-gray {
    background-color: #333!important;}
