Navlinks Change Color On ONE particular section

Hi Guys !

I am trying to get my navlinks, on the vertical navbar on the left to be BLACK on ONE particular section, the one with the white background. (these are three sticky sections)

I can’t manage to get it done right. I tried with the interactions but … no.

Any help would be appreciated ! With custom code I am sure it would be doable !

Thanks in advance
