ZorinOS/zorin-desktop-themes — reverse-engineered prompt

Build me a desktop theme pack for Zorin OS that gives the same overall Zorin look in a bunch of color choices, with both dark and light versions for each one. I want it to feel polished and consistent across the whole desktop, so windows, controls, menus, panels, and other common interface pieces should all match instead of feeling like a rough color swap.

Please include the theme variants that seem to be part of this project, blue, brown, green, grey, orange, purple, red, and yellow, each with a dark and light option. Make it easy for someone to install and switch between the themes without needing to tweak files by hand.

Keep the design clean, modern, and close to the default Zorin style, just with the different accent colors. If anything is missing or unclear, use the existing theme folders as the source of truth and look up current Zorin theming expectations online if you need to. I mainly want a complete, usable theme collection that feels like an official set.
