It is important to note that colors as such do not exist and the whole world is actually shades of gray. Do not rush to minus - this is a scientific fact and I will try to explain it at the very least. Physically, all colors are just light with different wavelengths. If it's very simple, then this light goes to the object, is reflected from it and then gets into your eye where it is actually processed. Actually, depending on various factors such as the angle of incidence / reflection of light, what you see is what you see. Just a bunch of objects of varying light levels. Color appears primarily due to the ability of our eyes to perceive different wavelengths and the ability of our brain to "label" these waves. Most animals do not do this, they see the world as gray and do not worry about it. All this is necessary so that our biological species can distinguish many different things from each other and divide them into edible and inedible. The same cow doesn’t need this skill, because for her everything that looks like grass under her feet is food, and everything else does not.
As for people, a person sees the world as his taught. If you were shown a little train as a child and said that it was red, you will perceive this color as red. The same engine in another family was called brown-crimson and for the second child it will be just that. The more colors will be shown to the child, the wider his color perception will be, and if the first child sees ten identical red balls, then the second will easily distinguish them by the shades imperceptible for the first. Therefore, in ancient texts, our ancestors, not spoiled by color diversity, used the word violet to describe the color of iron, the sea was wine red, and the sheep were the color of violets (if that is from Homer). In fact, for the people of that time, they could not distinguish bright blue from black, and pale blue from gray. for them it was all the same color.
Hence the conclusion - what you call green, you call it that, because you were taught to think that it is green. For another person, it will no longer be green, but some kind of light green or light green. So when you explain in the store what color of wallpaper you need, take a sample with you.
The name for the "new" color in all eras was invented by enthusiasts due to the need to describe important characteristics.
Initially, concepts arise in the languages of primitive people "light" and "dark". Then the "red" color is isolated, because blood is the most important sign of life. Then "yellow" and "blue-green" appear, which later splits in two. The name blue is probably associated with the sky, and green and yellow with grass, leaves and other vegetarianism.
The need for deep differentiation of flowers (and their names) is caused by most likely, technological development. Most flowers of natural shades are named by analogy with the fruits and flowers of plants, minerals, etc., which already have their own name. Like: brown, pink, lilac, purple, orange ... Others are borrowed from foreign languages directly (some kind of azure).
Among the color names there are also modern , i.e. e. specially invented (like, "electr and k").
