In a world where every person can only see in a spectrum of color that corresponds to the height of what they're observing, Tao and Lakshmi are in a room with a red ceiling and a blue floor. Everything else in the room is grey. If Tao is standing and Lakshmi is sitting, what can each person see in color? Provide a brief response.
Tao, being taller while standing, can see the ceiling at a higher eye level. Since the ceiling is red and color perception is linked to the height of the objects, the ceiling would be within Tao's visible color spectrum. Therefore, Tao can see the red ceiling but everything else at his eye level or below appears grey to him, including the blue floor and grey walls.

Lakshmi, who is sitting down, has her eyes at a lower height closer to the floor. Thus, the blue floor falls into her visible color spectrum. Lakshmi can see the floor in color since it is currently level with her line of sight or height. Conversely, Lakshmi would see the ceiling in grey as it is higher than her sight line and does not match her visible spectrum based on her height.

Hence, Tao can see the red ceiling in color but not the blue floor, while Lakshmi can see the blue floor in color but not the red ceiling.
