"Poppy pollen. Opium."
—Ojo to Dorothy
The Brick Road is covered with poppy pollen, responsible for its yellowish appearance. The bricks themselves are regular color.
- In the leaked script for the Pilot, the road is made of golden bricks. Gold is considered a rock like any other.
- The road we can see on-screen is in fact made of rubber and can be rolled in and out when the production requires. The yellow dust is sawdust, dyed to yellowish tint.
