The icon of the butterfly is inspired by the stunning Australian butterfly, the Ulysses Mountain Blue. This butterfly's dull brown underwings open out to a shimmering iridescent blue, which is represented with a vivid metallic blue ink across the company stationery and vehicle signage.

The name Calypso is derived from the ancient Greek myth, The Odyssey. "Kalypso" was as a neried (sea nymph) who fell in love with the hero, Odysseus - or "Ulysses", in Latin.
