Crimson & Burgundy & Cerulean

Cerulean and Burgundy share a quality of serious depth — both are dark enough to carry formal weight while Cerulean retains its warm-blue atmospheric quality. Against Burgundy's aged wine-dark, Cerulean creates the impression of deep maritime water seen from a harbour at dusk: the dark warm red of the dock buildings and the deep warm blue of the harbour water meeting in the fading light, with Crimson as the vivid point of the setting sun's last intensity. The palette creates a maritime dusk atmosphere — the most formally sophisticated and most atmospherically rich combination within the warm-red-and-atmospheric-blue tradition.

The palette is the visual world of the Portuguese Age of Discovery (Era dos Descobrimentos, 1415-1543) — the most historically significant maritime exploration program in European history, when Portuguese navigators including Bartolomeu Dias, Vasco da Gama, and Ferdinand Magellan opened the sea routes to Africa, India, Brazil, and the Pacific. The Portuguese imperial tradition combined the deep burgundy-red of the royal House of Aviz's heraldic tradition (the crimson-and-burgundy of the Portuguese royal standard) with the cerulean-atmospheric-blue of the Atlantic Ocean and the Indian Ocean that defined the Portuguese maritime empire. Portuguese azulejo tiles — the famous blue-and-white ceramic tile tradition that became the definitive visual identity of Portuguese culture — use exactly the cerulean-blue against white or against deep warm grounds in the most complex narrative panels depicting the discoveries.
