The position of the sun can affect the appearance of rain clouds, but it doesn't necessarily make them appear darker. As I said, the darkness of rain clouds is primarily determined by the amount of water droplets or ice crystals they contain and the thickness of the cloud. When clouds are thicker and have more water or ice, they can appear darker because they absorb and scatter more light.

However, the position of the sun can affect the angle at which the light hits the clouds, which can influence their appearance. For example, when the sun is low on the horizon during sunrise or sunset, the light can pass through more of the atmosphere before reaching the clouds. This can cause the light to be scattered more and create a reddish or orange tint to the clouds, which may give the appearance of darker clouds.

Additionally, when the sun is directly behind the clouds, it can create a backlit effect that can make the clouds appear more dramatic and pronounced, although not necessarily darker.

So, while the position of the sun can play a role in the appearance of rain clouds, the darkness of the clouds primarily depends on their thickness and the amount of water or ice they contain.
