Ramp 1 which is connected to Charles Darwin's Labatory.

Charles Darwin's space is build in the deepest inside.
Therefore, it obviously does not have natural light to have brightness in the room.So the sapce has a strong man made light coming from down to suit the concept
that it is adaptable to its environment.

Texture to emphasise the dungeon like environment.

Lights coming from ramp 2.

In Darwin's space, all lights are not direct but artificial or indirect
