Change footer link color depending on page hero

Hey,
I need your help once again. Is there any way to change the link-color of the footer-links depending on the active page-hero, too?
It did not work with the settings in the Page Hero Element.

I thought it might work with

.hero1 + .site-footer a {
    color: #fff;
}

but that didn´t work either.
Any other ideas?
Thank you in advance :)
