There are different answers of this question.
I think the answer could be water because if you observe water in the day you will see due to glass it will appear green and in the afternoon it will be black due to shadows or the sunlight. In evening it seems to be blue due to the colour of the sky and in night it is white due to the colour of the Moon.
so I think it is the answer.
plzzzzz mark as brainliest if it is right.
