Not really. Silicate clouds are expected to be quite common in hot jupiters (hyperthermaljovians, in OA nomenclature).
Planets with Sudarsky class V characteristics

would have silicate clouds and silicate rain.
The colour of a class V planet is expected to be blue

However I note that HD 189733 b is supposed to be a Sudarsky class IV, which are supposed to be dull maroonish-brown; obviously there is a certain amount of overlap between the classes...
