Venus is seen as a perfectly white ball illuminated by the Sun. The lack of details on it indicates that the surface of the planet itself is not visible. The silvery-white color can only be explained by the reflection of sunlight from particles of solid or liquid matter suspended in the atmosphere. If the reflection came from a layer of dust, then the planet would have a reddish tint due to absorption of the short-wave part of the spectrum. Hence it follows that the clouds of Venus are of a droplet-liquid nature.
