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.
A dark rain cloud is called a nimbus. These clouds produce rain and snow as they are filled with compact and frozen moisture.
The names of the groups of clouds that can produce rain are nimbostratus and cumulonimbus. The nimbostratus clouds are the ones we see that become very dark and produce a lot of rain or snow. The cumulonimbus clouds are responsible for lighter rain and thunderstorms.
Nimbostratus clouds and cumulonimbus clouds are the two main types of clouds that produce rain. Nimbostratus clouds are thick, dark clouds that cover the sky and bring steady, prolonged rain showers. Cumulonimbus clouds are large, towering clouds associated with thunderstorms, which can produce heavy rain showers, lightning, and thunder.
Rain clouds...obviouly!
I believe this question was intended to be: "Do cumulonimbus and nimbostratus clouds produce rain or snow?" The answer to this question is: "Yes, both types of clouds CAN produce precipitation, including rain and/or snow, depending on the temperature in the atmosphere."

Nimbostratus clouds typically give continuous rain due to their large, thick, and dark appearance. These clouds can cover the sky for long durations and produce steady precipitation.
Cumulus clouds can develop into rain clouds, but they do not typically produce rain on their own. When cumulus clouds grow larger and combine with other clouds, they can form cumulonimbus clouds that produce precipitation.
Nimbus … rain clouds
Cirrostratus clouds art the least likely to produce precipitation that reaches the ground. These clouds are often formed from cirrus clouds as a warm front approaches.
Rain clouds, also known as nimbostratus clouds, are low- to mid-level clouds that bring precipitation. Storm clouds, such as cumulonimbus clouds, are tall and dense clouds that can bring heavy rain, thunderstorms, lightning, and sometimes hail or even tornadoes. Both types of clouds are associated with weather systems that can produce significant precipitation and severe weather.
