Anyone with a address gets View access everywhere by default. Add someone below only if they need something different — a specific tab hidden, or write access to one tab without making them a full admin.

Five colors for the public forms (inquiry, apply, crew info) and the deal workspace. The hub pages keep their own fixed look. Everything else (borders, muted tints, hover states) is derived automatically; some combinations will read better than others. The preview below changes as you pick, and saved colors reach everyone the next time they load one of those pages.
