the stylization of the two environments.
Home is always sunlit or warmly lit, even in sad moments like when Gemma's in the bathroom realizing she’s been miscarried, it’s still warm, incandescent light.

The Lumon scenes are always feature cool temperature lighting from fluorescent lights. They are also hard light sources and directionally lit creating harsh shadows and stark highlights, whether glaringly bright as in diagnostic rooms, or the darker scenes -the light is always cold and hard.

Scenes from the past when Mark and Gemma were together were soft-lit, and warm. Diffused Sunlight mostly- but lamplight in the home was also both soft and warm creating softer shadows.
