Nombeko's room is still fairly dark when they wake up early one morning. They look over at their shirt hanging on a
hook. Nombeko knows it is their red shirt because they hung it up there before they went to bed, but in the dark,
Nombeko can't see its color. It looks dark gray to them. Why is that?
Their pupils do not dilate in the darkness.
Their optic chiasm does not function well in darkness.
In the dim light, the rods in their eyes are ineffectual.
In the dim light, the cones in their eyes are ineffectual.
