A person wearing dark blue and holding a bright red umbrella is reflected in the rainy pavement.
The person is holding the umbrella inside the windowless building.
The person's image cannot be reflected on the pavement if the person is inside a windowless building.  Without the window, there is no way for the image to reflect outside on the sidewalk.
