Why do clouds sometimes look dark?

Clouds look dark when they are thick and contain a lot of water droplets or ice crystals. These dense clouds block sunlight from passing through, making them appear darker. This is common with rainclouds, which have more particles and absorb or scatter light, preventing it from reaching the ground.
