Clear ground has no blend family of its own — it is what the other families blend against — but its first tile is the one the engine substitutes whenever a cell has no tile at all. Such a cell borrows it for its map preview color, its radar color, and the tile it draws with. Leveling terrain flat writes it into every cell that comes out unramped, and a map that gives no [Map] Fill= value, or gives any value other than Water, is filled with it before anything else is placed.
