Did ancient humans see blue?
Scientists generally agree that humans began to see blue as a color when they started making blue pigments. Cave paintings from 20,000 years ago lack any blue color, since as previously mentioned, blue is rarely present in nature. About 6,000 years ago, humans began to develop blue colorants.
“During the period between 45 and 30 million years ago, [the human pigment that had been UV sensitive] was in the final stage of developing its blue-sensitivity.
On the other hand, since yellow is the most visible color of all the colors, it is the first color that the human eye notices. Use it to get attention, such as a yellow sign with black text, or as an accent.
As we know, the human eye has three types of cones that allow us to see a certain range of light, and, therefore, colour, on the electromagnetic spectrum—i.e., the visible light spectrum. These colours are blue, green, and red.
So while people in the Homeric period could only distinguish between red, orange, and yellow, by the nineteenth century the European eye was able to see blue and violet. But while European eyes were now able to see the full spectrum of colours, that didn't seem to be the case for non-European eyes.
Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously.
Greeks certainly could see the color blue, but they didn't consider it separate from other shades, such as green, complicating how exactly they perceived the hue.
In early medieval Europe, blue was a royal and aristocratic color, as blue dyes were rare and expensive.
The human eye can only see visible light, but light comes in many other "colors"—radio, infrared, ultraviolet, X-ray, and gamma-ray—that are invisible to the naked eye.
The blue side reflects blue light. The wavelengths that don't bounce off get absorbed as heat. Only the colors that bounce off reach your eyes. The color of light coming from an object is what gives it color.
Did ancient people see colors differently?
Their color receptors were certainly identical to ours, so on the most basic level, their perception was no worse than ours; their eyes perceived the same wavelengths of lights ours do. Our eyes can perceive the color blue even if we don't have the word.
Actually, the sky was orange until about 2.5 billion years ago, but if you jumped back in time to see it, you'd double over in a coughing fit. Way back then, the air was a toxic fog of vicious vapors: carbon monoxide, carbon dioxide, nitrogen, cyanide, and methane.
In the ancient Egyptian language Egyptian blue was known as hsbd-iryt, which means artificial lapis lazuli.
Blue didn't appear in Chinese stories, the Icelandic Sagas, or ancient Hebrew versions of the Bible. The Ancient Egyptians, however, did have a word for blue. They were also the only ancient culture to develop a blue dye and commonly use blue in jewelry and ornaments.
Forty-nine times the Bible mentions a perfect, pure blue, a color so magnificent and transcendent that it was all but impossible to describe.
It was bronze. Ancient Greeks were not colour blind, but instead of thinking in colours, they thought in a scale of brightness – and to them the sky seemed incredibly bright, just like shiny bronze plates.
Bits and pieces of the opsin genes change and vision adapts as the environment of a species changes. Around 90 million years ago, our primitive mammalian ancestors were nocturnal and had UV-sensitive and red-sensitive color, giving them a bi-chromatic view of the world.
Yes. The Greeks were able to distinguish shades of blue just as vividly as we can now, despite lacking a specific vocabulary for them.
Greeks certainly could see the color blue, but they didn't consider it separate from other shades, such as green, complicating how exactly they perceived the hue.
Original Greeks were blonde and blue eyed...they later got darker due to the turkish influence. Having lived in Veroia for a few years I can say that there is a distinct blonde hair and blue eyed characteristic of the Macedonians. Of course they were blonde !
Which colour Cannot be seen by humans?

Blue in parts of Europe, at least, had long been associated as a feminine colour because of the supposed colour of the Virgin Mary's outfit."
Egyptian blue in use
In the Middle Kingdom (2050-1652 BCE) it continued to be used as a pigment in the decoration of tombs, wall paintings, furnishings and statues, and by the New Kingdom (1570–1070 BCE) began to be more widely used in the production of numerous objects.
Considered to be the first ever synthetically produced color pigment, Egyptian blue (also known as cuprorivaite) was created around 2,200 B.C. It was made from ground limestone mixed with sand and a copper-containing mineral, such as azurite or malachite, which was then heated between 1470 and 1650°F.
The Ancient Egyptians created the first blue pigment around 2,200 B.C. They heated a mixture of sand, ground limestone and copper-containing minerals like malachite or azurite at a high temperature. This process created an opaque blue glass that was crushed and combined with a thickening agent to make glaze and paint.
