When Did the Sky Turn the Color Blue?

The color blue is found primarily in nature. It’s in the light blue of the afternoon sky and in the deep variations of a lake or the ocean. But otherwise, there are very few blue animals, and it is the rarest of human eye color. Moreover, there are very few blue flowers that are not dyed by florists.

In my opinion, one of the most exciting developments in genetic engineering is in the development of blue flowers.

The Development of Genetic Engineering to Produce Blue Flowers

In 2017, a report was published in the Science Advances Journal. The scientists work at the National Agriculture and Food Research Organization in Japan. Their report reveals that they genetically engineered a blue chrysanthemum.

Also, thanks to the Australian company Florigene and the Japanese company Suntory, there is now a blue rose. In fact, they teamed up to genetically modify the world’s first true blue rose in 2004. However, although the flower is genetically blue, it appears purple.

The reason it’s so difficult to create a blue flower lies in the molecule known as anthocyanin. Anthocyanin is a blue pigment that easily shifts towards red or purple. How much it shifts depends on the sugar molecules that attach to it or other factors in its environment. These variables are what keeps more blue flowers from being developed.

“Blue thou art, intensely blue; Flower, whence came thy dazzling hue.”

Peace • Tranquility • Relaxation

This is a color that affords peace and tranquility while it promotes both physical and mental relaxation. Interestingly, some people believe a person who loves this color is the rescuer of a friend in need. They are also thought to nurture relationships with strength and trust, but is deeply hurt when the experience betrayal.

The #Fascinating History of the Color Blue

In the past and for centuries people used indigo plants to dye textiles bluish colors. But the thing about indigo is that it’s a bluish-purple color – not a true blue. In fact, the color indigo falls in the light spectrum right between blue (475 nm) and violet (400 nm).

Did you know that it is thought by historians to be the most recent color humans are able to perceive? This begs the question, when did the sky turn blue? Of course, I say that tongue-in-cheek, absolutely, but it does give pause for wonder. 👀

Seriously though, it is the general current consensus among scientists and historians that our ancient counterparts did not see the same range of colors that we see today. Below are some quotes about how humans were or were not able to perceive blue throughout ancient history.

How the Greeks Saw Their World

“Homer used two adjectives to describe aspects of the colour blue: kuaneos, to denote a dark shade of blue merging into black; and glaukos, to describe a sort of ‘blue-grey’, notably used in Athena’s epithet glaukopis, her ‘grey-gleaming eyes’. He describes the sky as big, starry, or of iron or bronze (because of its solid fixity). The tints of a rough sea range from ‘whitish’ (polios) and ‘blue-grey’ (glaukos) to deep blue and almost black (kuaneos, melas). The sea in its calm expanse is said to be ‘pansy-like’ (ioeides), ‘wine-like’ (oinops), or purple (porphureos). But whether sea or sky, it is never just ‘blue’. In fact, within the entirety of Ancient Greek literature you cannot find a single pure blue sea or sky.

The Sea was Never Blue

“Today, no one thinks that there has been a stage in the history of humanity when some colors were ‘not yet’ being perceived. But thanks to our modern ‘anthropological gaze’ it is accepted that every culture has its own way of naming and categorizing colors. This is not due to varying anatomical structures of the human eye, but to the fact that different ocular areas are stimulated, which triggers different emotional responses, all according to different cultural contexts.”
