📜 Origin & History

Sea Blue is directly sampled from the deep ocean under clear sunlight. In ancient Greece, where navigation was limited, the sea represented the unknown and divine realms. Sea blue adorned Poseidon temple reliefs and wave patterns on black-figure pottery.

The Age of Discovery in the 15th century saw Portuguese and Spanish explorers mapping unknown seas with sea blue—gradually becoming the visual recorder of geographical discoveries and colonial expansion.

In Romanticism, sea blue acquired emotional tension. Caspar David Friedrich's Monk by the Sea uses vast sea blue to express nature's desolation and sublimity, with humans insignificant as dust.

In modern marine biology and environmental movements, sea blue is the color of ocean conservation appeals. Non-profits like Ocean Cleanup use this undeniable pure sea blue to awaken public concern about plastic pollution and coral bleaching.
