not a lay theme person, just trying to help:

You can add "mix-blend-mode: difference" as css to the site title and nav:

.sitetitle, .laynav, .project-arrow, .mobile-title {
    mix-blend-mode: difference;
}

^ css you want to add! But the text needs to be WHITE to properly invert (so make your nav and title link colors white.

I kindof like how it looks without a transition lol - so keeping it off! BUT I did test the overlay links with a transition and it WORKS! Whatever you did fixed it!

HAH! That worked! That's what I get for revising this site over the years and leaving old code all over the place.

I'll dig through all the custom code and find whatever's doing it! THANK YOU ARMIN!

@arminunruh For now disabling the WP Fastest Cache.

Thank you SO MUCH for all the work on the overlay. its super super cool :pray:
