The Exploring Tarot set comes with a book that actually references the enhanced colors in the Radiant deck specifically. For instance, when it describes the Fool’s yellow sky as representing optimism, you can actually see that vivid yellow. The 272-page book (more than your average little guidebook) has spread diagrams that match the included layout sheet exactly - they clearly designed them together, not just bundled random components.
To be fair, I think most modern Tarot decks have good-quality guidebooks now.
