Livnat ha-Sappirלבנת הספיר

The first palace: the sapphire pavement seen under God's feet at Sinai (Exodus 24:10) — entry-level radiance, where prayer first leaves the atmosphere. The Zohar stations here the spirits that meet ascending prayer and the souls of converts. Rule of the whole ascent: the door is the same color as the floor of the vision that opened the tradition.
