Simulation of the changing visual appearance of an East-oriented Stained-glass window depending on the daylight color and orientation:

7:30 AM: before the sun rises, the sky illuminates the window

7:45 AM: a yellow Sunlight reaches the window

8:00 AM: the Sunlight is already whiter

12:00 AM: the Sunlight is white

12:30 AM: the Sunlight disappears, only the sky illuminates the window

4:00 PM: idem

6:00 & 8:00 PM: the sky’s color changes slightly

All this has been simulated using physical data about the light of the Sun and the Sky in the south of France, and physical data acquired by scanning colored glass with a spectrophotometer.
