Dropdown Menu color (on single page) Squarespace 7.1

Site URL: https://capybera-ranunculus-8edf.squarespace.com/merch

The dropdown navigation has white text & a cream background (image attached). I'd like for the dropdown background to match the header's forest green (#325241).

My header currently has this Page Header Code Injection to set the background to forest green:

Quote

<style>
#header {background-color: #325241 !important;}
#header a {color: #ffffff !important;}
</style>

It'd be greatly appreciated if anyone can find any workaround for me to change the dropdown menu color using CSS for just this page.

It looks fine to me. Did you solve it?
