It's an oldie but a goodie, "Keep the Home Fires Burning".
Clouds appear dark before a storm because they become thicker and higher, blocking more sunlight from passing through. This creates a shadow effect and gives the appearance of dark clouds. Additionally, the moisture content in the clouds increases as a storm approaches, which can make them appear darker.
Because there can be a lot of water in warm air, stratus clouds can easily turn into dark, rain and snow-producing nimbostratus clouds.
Because up in the air it is so cold that the water turns into a cloud. The dew inside the clouds keeps building up inside the cloud but doesn't turn to a gas. And when the cloud is to heavy it rains.
The optical thickness increases when the cloud grows thicker and is filled with liquid or frozen water. It is more difficult for solar radiation to pass through the cloud, so it appears dark on the bottom.
It depends how dark they are. Check the label for washing instructions, turn them inside out, or be on the safe side and wash them with colors.
Clouds usually start as small flecks and then turn to thin clouds or massive storm clouds.
The clouds turn pink and purplish at sunset because the light becomes polarized.
No
Clouds already consist of tiny droplets of water or ice crystals.
It's all about the lighting. I find that my pictures best turn out when I take them outside, when it's sunny out. At night time, or inside, or anywhere dark, pictures won't turn out as good. You can put your picture onto your computer (if your camera is digital) and mess with the lighting on photoshop, but it doesn't always turn out still.
