I WONDER - Why Are Clouds White?

Clouds change color based on how they interact with sunlight. Grey clouds form when water droplets block light. Pink clouds appear during sunset or when filled with snow due to frozen water reflecting sunlight. Green clouds can signal storms or tornadoes, as thick storm clouds filter out red light, allowing only green and blue light to pass through.

How do storm clouds indicate the possibility of thunderstorms or tornadoes?

Explain why the sky in clouds can look green during storms.
