Color changes of sunny and rainy flowers in sunny and rainy days

Rain flower is a blue flower on a sunny day and turns into a purple flower before it rains; It turns into a pink flower when it rains. Rain flower is actually a chemical phenomenon. The paper used to make this bottle of flowers is soaked in diamond dichloride solution.

The substance dichloride diamond is eccentric and particularly sensitive to water. At room temperature, anhydrous dichloride diamond is blue, but it is easy to absorb moisture in the air. Once it absorbs water, it becomes a complex of pink diamond. When the weather is clear, there is little water in the air, and diamide diamonds are difficult to absorb water, which is blue: before it rains, the water in the air increases, a small amount of water is absorbed, and some chlorinated diamonds become diamond complexes. At this time, the blue and red colors are mixed and purple; When it rains, the moisture in the air increases sharply, making all the dichlorodiamonds in the flowers become diamond complexes, showing pink. You can tell whether the weather is sunny or cloudy according to the color change of this bottle of sunny flowers.
