Changing Background, Button & Font Colors for My Account menu, page, and Wishlist

Hi,

I am using the Cosmetic 3 layout and customizing it to be dark.

Link (click purple button): https://beardkingbrotherscom.skipdns.link/

Can you help me with the following:

1. Change the bg and font color for the 'My Account' dropdown menu?
2. My Account page: change link colors and BG
3. Button Color in Orders & Wishlist
4. Slide Cart Colors: bg, font and button

I have tried playing with the color settings in theme options, but need some help to point me in the right direction.
