The light is glowing through the light well into waiting room, just like colors filling in pigment needles. The color extends from floor to wall then up to ceiling, each filled pigment needle is introducing people into the room.
The tattooists advocate trees, and trees represent eternity.
I used silhouette trees as the design language of the ceiling and the walls, which are related to those plants under the center light well. The lighting has multi layers and from different directions, that gave tattooists uniform light sources.
