Moonlit grey-brown, the colour of a nightjar's wings, silent in flight.
Nighthawk is a warm grey.
It can be described as warm, muted, greyish and dusty.
Set in white, because white reads best on it.
Nighthawks are ten New World species of nightjar in the family Caprimulgidae. They have short bills and generally lack the elongated rictal bristles that are present in other nightjars. They also tend to be less nocturnal than other nightjars and can be observed feeding at dawn and at dusk.
