Symbolism of Blue

In the “Odyssey”, Homer famously describes the “wine-dark sea.” Well, that’s poetic, isn’t it? But there’s a reason he didn’t just call the ocean blue. There was no term for ‘blue’ in Ancient Greece. People from antiquity didn’t consider blue a separate colour significant enough to name. It’s difficult to find a word that meant ‘blue’ way back in time. Black and white are mentioned a lot. Red, a little, next green and yellow. But no blue! Blue is one of the primary colours. In Japan there’s ‘midori’, which today means green (think of the liquor) but which is traditionally a sort of bluish-green colour, somewhere in the middle. Midori is traditionally ‘the colour of nature’, and describes the color of shoots, young leaves, or whole plants. There is a Japanese word for blue (ao). But educational materials distinguishing green and blue only came into use after World War II.

Every language first had a word for black and for white, or dark and light. The next word for a colour to come into existence — in every language studied around the world — was red, the colour of blood and wine.

After red, historically, yellow appears, and later, green (though in a couple of languages, yellow and green switch places). The last of these colours to appear in every language is blue.

What else remains a significant conceptual gap in our culture, just waiting around to be named? And then, once it’s named, we won’t know how we rubbed along without it.

The Romans did not have a symbol for nothing (zero), and were so hampered by the lack that they were incapable of contributing to mathematical knowledge.

With our contemporary conceptions of colour, the sky can appear a vast array of different colours, but we mostly associate ‘sky’ with ‘blue’. Historically, we therefore associate blue with the heavens.

Various other associations come from that main connection:

  • truth and the intellect
  • wisdom
  • loyalty
  • chastity
  • peace
  • piety
  • contemplation


No surprise either, then, that blue is the colour worn by images of the Virgin Mary, who is supposed to embody all of the qualities in that list. If you see a young woman in a blue dress in a work of art, the work may be utilising the purity associations of the Virgin Mary.

Blue is the symbolic inverse of the reds, oranges and yellows, which indicate carnival and fun. Blue has many variations but tends towards sober and sombre. Blue is also therefore associated with melancholy, loneliness, regret, saudade and related emotions.

In music, ‘blue’ describes notes pitched a little lower to evoke those emotions. Billie Holiday’s Strange Fruit is a wonderful example of juxtaposition for devastating emotional effect: The colours described in the lyrics are bright and sunny. That helps the images of bodies hanging from trees to feel appropriately shocking. The images and the blue notes juxtapose against the romantic ‘pastoral scene of the gallant South’.

The painting below is an excellent example of blue used as juxtaposition against warm hues. In art this is known as making use of complementary colours. (Colour choice is scientific when it all boils down.)

Though blue often indicates difficult emotions, it can indicate the inverse equally well. For instance, the bluebird is a widely recognised symbol for happiness. In the painting below, the patch of blue sky above indicates a break in the weather and is clearly a welcome sign against the murky, greenish blue of the churning water.

A clear blue sky generally means ‘infinite possibility’ and in this way, sky blue symbolises hope.


In Jewish tradition Immortals lived in the city of Luz, also known as The Blue City. This is connected to the idea of blue as endless, never-ending space.


According to Hindu tradition, Mount Meru is a mythical sacred mountain. The southern face is supposed to be made of entirely of blue sapphires. This explained to Hindus why the sky is blue — the sky is a reflection of the southern face of this mountain.

Sometimes, when something that isn’t normally blue is indeed blue, this is a representation of the impossible. The blue rose is a good example of ‘blue as impossible’.

A fairytale like Bluebeard takes the colour blue and applies it to a human. This human is considered an abomination — more monster than person. The blue tinge of his beard is a physical manifestation of his unnaturalness.

Green is used in a very similar way in other stories. Cf. green witches and green aliens, and the green skin of The Incredible Hulk.


The blue hour (from French) is the period of twilight (in the morning or evening, around the nautical stage) when the Sun is at a significant depth below the horizon and residual, indirect sunlight takes on a predominantly blue shade, which differs from the one visible during most of a clear day, which is caused by Rayleigh scattering.

For the illustration below, Tom Lovell repurposes the concept and applies it to that time of day when Mother has had enough.

The Romans traded for lapis lazuli which was mined in Afghanistan as it still is today.  They named the stone after its long journey from the east across the Mediterranean “Ultramarine blue” not because it looked like the blue of the sea but, because it came across the sea to Rome.

Bluebells were a very common home for fairies around the time of the first world war? Why? [Perhaps the colour blue indicating virginity and purity had something to do with this choice of flower.]


The phrase ‘blue stocking’ comes from the late 17th century and, like the word ‘tomboy’ originally described a man rather than a woman. These men woreblue worsted (instead of formal black silk) stockings. This was extended to mean ‘in informal dress’.

Later the term denoted a person who attended the literary assemblies held ( c. 1750) by three London society ladies, where some of the men favoured less formal dress. The women who attended became known as blue-stocking ladies or blue-stockingers.

Then the phrase was used to insult intellectual young women who were more interested in ideas than in getting married.

It has since been reclaimed.
