Obsidian publish highlight color of TOC links

building my publish site and can’t seem to figure out what selector to use to style the highlight color of links in the TOC. you can pick the header link and the page scrolls to that section with a yellow background that slowly fades away. i want to change the yellow to something else.

in the desktop app you can target .obsidian-search-match-highlight and adjust background color, but that doesn’t work on the published site.

any ideas?
