Grey-blue sky where homing pigeons once carried the mail, small envelopes tied to their legs.
Pigeon Post is a pale grey, close to blue.
It can be described as pale, delicate, faded and unsaturated.
Set in black, because black reads best on it.
Pigeon Post is an English children's adventure novel by Arthur Ransome, published by Jonathan Cape in 1936. It was the sixth of twelve books Ransome completed in the Swallows and Amazons series. He won the inaugural Carnegie Medal from the Library Association, recognising it as the year's best children's book by a British subject.
Read on WikipediaPigeon post is the use of homing pigeons to carry messages. Pigeons are effective as messengers due to their natural homing abilities. The pigeons are transported to a destination in cages, where they are attached with messages, then the pigeon naturally flies back to its home where the recipient could read the message. They have been used in many places around the world. Pigeons have also been used to great effect in military situations, and are in this case referred to as war pigeons.
