Simple 2.2.3.0 lacks color option for Footer and Header

I wonder why the options are gone. They were there before and i relied on them. I fear further updates if things like this where changes constantly.

Link and text color is now fine but i wonder how to change the overall background color. Could you give me a hint?
Previously i changed the visual-override.js with this code, but its not working anymore:

if (params.minFontSize !== '1.1' || params.maxFontSize !== '1.2') {
output += `
body {
  background: #EEE8D5;
}
.site-container {
  background: #EEE8D5;
}
}`;
}
