ah very good!
also i noticed on iphone / mobile version
the mix blend mode didn't work for the site title
i noticed, mix blend mode may only work if the text that its applied to is a direct child of the body
so with this HTML it works:
<div class="mobile-title">Hello!</div>
but with this it doesn't:
<div class="mobile-title"><span>Hello!</span></div>
so for mobile to make it work for a site title on phone, you can use this script and css
in lay options -> custom css & html at bottom:
<script>
jQuery(".mobile-title span *").unwrap();
</script>
<style>
.mobile-title{
mix-blend-mode: difference;
}
</style>
