Because they are thicker making it hard for light to travel through
the darker clouds have got rain in and the lighter clouds have nothing in them
The darker clouds have evapouated more water from the land so they are more heavy.
Some clouds are darker because of the lack of sunlight. Some clouds are blocking the other clouds and it forms a shadow and that the cloud won't get sunlight. Also that if the cloud is darker, because it is pollution. Pollution is like an evil dye that no one likes because it also has a lot of chemicals in it. That is why NEVER DRINK RAIN WATER! The darker clouds have water (rain) in them, where as the white ones are just empty.
they are not.
Because of shadows made by craters.
there is no other cloud higher than a cirrus cloud

They are colder and darker than the other areas
They are features that are darker than other features such as if you were in a cave and the far side is darker than the other side than that is the low level image feature. ( they can be in any rainforest and in any caves or oceans.)
The bigger the droplets of water in a cloud the more light is absorbed. The more light absorbed the darker the cloud.

Some clouds are darker because they are rain clouds. After the air condenses to its dew point, the water vapor that is no longer needed will form a liquid form of water, which in this case would be a cloud. The cloud would be full of water. When it can no longer hold the water, it starts to rain. The cloud is white when the sun shines on it. It becomes dark when the sky is dark, and then the thunder and rain comes.
