Clouds don't turn dark. They get larger and thicker and cover the sun more effectively, and that makes the bottoms of the clouds appear dark and makes it dark underneath them.
Dark billowing raining clouds are often referred to as storm clouds. These clouds typically bring heavy rain, thunder, and lightning as part of a storm system.
The dark clouds were foreshadowing the storm that was to come.
Nimbus clouds can appear dark and ominous, especially when they are associated with storms or heavy rainfall. They are thick, dense clouds that can cover the sky and bring inclement weather. However, not all nimbus clouds necessarily indicate a severe storm, as there are various types such as nimbostratus clouds that produce steady rainfall.
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.
Clouds can appear dark due to thickness and composition, with thickness leading to light being blocked and composition causing absorption of light. The color of clouds can range from dark gray to almost black depending on the amount of sunlight they block and their water content, with storm clouds typically appearing darker due to their density and water concentration.

cumulonimbus
Storm clouds appear dark because they are thick with water droplets and ice crystals that block out sunlight. This causes less light to pass through the cloud, making it appear dark from below.
Clouds usually start as small flecks and then turn to thin clouds or massive storm clouds.
The dark clouds were foreshadowing the storm that was to come.
The dark storm clouds foreshadowed the approaching bad weather.

Dark storm clouds were looming on the horizon, casting a sense of impending doom over the peaceful village.
Cumulonimbus clouds are storm clouds.
Nimbo clouds produce rain. Nimbostratus clouds are full of water, so sunlight cannot get through it, that is why the sky is dark when there are storm clouds above.
Dark rain clouds typically indicate an impending storm with heavy rain. The clouds are full of moisture and are usually seen before a downpour. It's a sign that inclement weather is on the way.
Clouds are dark without rain when they do not reach their dew point, the temperature at which water condenses to create rain.
