Clouds that are dark on the bottom are likely cumulonimbus clouds. That word comes from cumulus and nimbus. Cumulus means light, or fluffy. They're the kind of clouds you look for shapes in. Nimbus means rain. So, fluffy rain clouds is a rough translation. Cumulonimbus clouds bring rain, and possibly a tornado if you live in that area. It might be a heavy rain or a harsh thunderstorm. Just get inside as fast as you can!
All clouds are darker on the bottom. However, the larger clouds that produce precipitation are called cumulonimbus. These clouds are extremely large and produce precipitation.
Any type precipatation falls out of dark clouds.
The light stripes are regions of high clouds, and the dark stripes are regions where we can see down to deeper, darker clouds.

Stratus clouds are uniform and ressemble fog at times. Usually there is no precipitation. Nimbostratus clouds are typically followed by rain causing them to be a darker grey color.
Pencils have had no lead for many years.Generally, a softer graphite will have a darker color.A pencil with a high "B" rating will be soft and produce a darker color.
A common indicator of an approaching thunderstorm is darkening skies, particularly if they quickly become significantly darker than the surrounding area. Thunderstorms are often accompanied by thickening clouds that can block sunlight, leading to a noticeable decrease in brightness. Additionally, a shift in wind direction and an increase in gustiness may also signal an approaching thunderstorm.
Cumulonimbus clouds
Because they are thicker making it hard for light to travel through
Thunder clouds are grey because they are denser and heavier than other clouds. Clouds are just clumps of moisture beads that form in the atmosphere. Clouds that cause thunderstorms tend to contain much more moisture than other clouds - they are thicker and heavier, and thus they appear darker because light cannot get through them.
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.
grey darker and lower
Yes, some rain clouds are dark grey or black, due to the fact that these clouds are very dense and big, also containing lots of water vapor. The density of the cloud and all the water vapor doesn't allow as much light through as a normal cloud does, giving it a darker appearance.
All clouds are white, meaning the water droplets that make up a cloud scatter light in all wavelengths so they combine to produce white light. Clouds appear dark if they are in the shadow of other clouds or, sometimes, if the top of the same cloud produces a shadow on itself. There is also a darker look to some clouds if the background color is bright sunlight, making a great contrast.
The darker the cloud... the more moisture it contains.
The light stripes are regions of high clouds, and the dark stripes are regions where we can see down to deeper, darker clouds.
