Question

Marlene wakes up early in the morning and her room is fairly dark. She looks over and sees her shirt hanging on a hook. She knows it's her red shirt because she hung it up there before she went to bed, but in the dark she cannot see its color. It looks dark gray to her. Why is that?

Answer 1

Answer: we see colour by light reflecting off our eyes, so it is likely that there was no light directly hitting her eyes, because she had just got up.
