In Latin, the choice of word for "blue" depends heavily on the specific shade and quality of the color being described. While caeruleus is the most common and general term, it specifically evokes the color of the sky or the sea. Other terms are used for more nuanced or specialized shades, ranging from the sea-blue of venetus to the dull, bruised tones of lividus.
Which one should you use?
The various forms in Latin provide specific color nuances: caeruleus is the standard term for sky-blue or sea-blue. venetus is a specialized term used for a deep sea-blue or dark blue, often associated with the color of the Veneti in chariot racing. For a duller, darker or bruised-looking color, use lividus to describe a bluish-grey or leaden tone. For shades that sit between blue, green and grey, such as sea-foam or certain leaves, use glaucus. Other forms include blavus (la-lat), azurinus (lapis, ML.), cyaneus (cyan) and caerulus, which is an alternative spelling of caeruleus.
