What color are red paper flowers in different weather?
the color is light in blue sky and dark in rainy days.
Salt absorbs water easily. In rainy days, the water vapor in the air is enough, and the salt on the paper flower absorbs more water, so the color of the paper flower becomes darker.
On sunny days, the water vapor content in the air is low, and the salt on the paper flowers can't absorb water, so the color naturally becomes lighter.
