Love it?

Back in ancient Greece, there was no single word that neatly captured the hue of the sky, the sea, sapphire, and blueberries all at once. But that’s less strange than it might sound. If you think about it, the English word “blue” covers a wide range of shades, from the palest robin’s egg to the deepest navy. 

While it’s sometimes reported that ancient Greeks had no word at all for this part of the color spectrum, they actually used several terms that correspond to what we call blue, including kyaneos for darker blue shades and glaukos for pale and mid-toned grayish blues and greens. However, these words could also refer to other hues and were more dependent on context than our modern color categories.

Plenty of languages divide colors differently than English. Russian distinguishes between lighter blues (goluboy) and darker blues (siniy), and modern Japanese has a specific term for light blue (mizu). And while it’s sometimes said that people in ancient Greece couldn’t see the color blue, they definitely could — assuming normal vision, of course. The eyes of ancient Greek people worked as well as ours, and they knew how to dye and paint with blue pigments. 

However, it’s true that blue was far less important symbolically in the ancient Greek world than red, black, yellow, and white. Blue tones generally only appear as background colors in Greek art, when they appear at all. But the Greeks did hold blue in higher regard than the Romans did; the latter considered it a color of barbarians and mourning. (Having blue eyes was considered practically a character defect.) Imagine how surprised they’d be to discover that today, blue is one of the most popular colors in the world.

By the Numbers

Did you know?

English had no word for the color orange until the 16th century.

For most of history, the color orange didn’t have its own name in English. Before the 16th century, English speakers typically described the hue as “yellow-red” or simply “red.” The word “orange” originally referred only to the fruit, and its linguistic journey began with the Sanskrit nāraṅga, the name for the orange tree. 

As the fruit spread west through trade, the word became the Arabic nāranj and eventually entered European languages. English lost the initial “n” through a linguistic shift called metanalysis, in which sounds migrate between words — the same process that turned “a napron” into “an apron” and “a nuncle” into “an uncle.” 

By the 1300s, “orange” was widely used across Europe to name the fruit. But according to the Oxford English Dictionary, English speakers didn’t begin using it to describe the color until the 1500s, often in reference to fabrics and clothing. Before that, the color existed as a unique hue — but it didn’t have a name of its own.
