People imagine that blue is common in nature due to the blue of the sky and oceans

Chemistry and physics sciences answer you. What is the reason for the scarcity of the color blue in nature?

When you look at the blue sky or across the endless expanse of blue oceans, you might think that blue is common in nature, but in fact of all forms, found in rocks, flowers,  plants or even in the feathers, fur and skins of animals, blue color is surprisingly rare.

But what is the reason for the rarity of this color in nature? The answer stems from the chemistry and physics of how colors are produced, and how we see them, and a Live Science report explains the secret behind this "elusive" color.

Egyptian blue was made by the pharaohs thousands of years ago, and its chemical properties were recently discovered Kai Kupferschmidt researched in his book the secret behind this "elusive" blue color (Live Science) seeing colors

We are able to see more color region because each eye contains between 6 million and 7 million light-sensitive cells box's called cones. There are 3 different types of cones in the eye of a person with normal color vision, and each type of cone is more sensitive to a specific wavelength of light: red, green or blue.

Information from millions of cones arrives in our brains as electrical signals that transmit all kinds of reflected light through what we see. A German scientific writer Kai Kupferschmidt says, When we look at a rear colored object, like a sparkling sapphire colored, it absorbs some of the white light color that falls on it, and reflects perfect the rest of the light as color.

Kupferschmidt, author of Blue color: In Search of Nature's system rarest color, wrote in his book, When you see a blue color flower, you see it blue  color because it absorbs the red color part of the spectrum.

In the visible spectrum, red color has long wavelengths, which means that it is very low energy frequency compared to other colors. For a flower to appear blue color, it must be able to produce a molecule that can absorb very small amounts of energy in order to absorb the red color part of the spectrum.

It is difficult for plants to produce such large and complex molecules, which is why blue flowers are produced by less than 10% of the world's roughly 300,000 flowering plant species.

One possible driver for the development of blue color flowers is that blue color is highly visible to pollinators such as bees, and blue color flower production may benefit plants in ecosystems, Adrian Dyer, associate professor and vision scientist team at the Institute of Technology collage in Melbourne, Australia country, Where competition for pollinators is high.

For metals element's, their crystal body structures interact with ions ( molecules or charged atoms) to determine which parts of the spectrum movement are absorbed and which are reflected. For example one, the mineral lapis lazuli contains of 3 sulfur atoms bound together within a crystal lattice that can release or bind one electron.

And the animals' blue colors don't come from chemical dyes. Instead, they rely on physics to create the color blue, as happens in animals such as poisonous blue-ringed octopuses. Blue-winged butterflies have complex, multi-layered nanostructures on the scales of their wings that manipulate layers of light so that some colors cancel each other out and only blue is reflected.

Blue colors in mammals are much rarer than in birds, fish, reptiles and insects. Some whales fish and dolphins fish have bluish skin body, and some are primates, such as golden snub-nosed monkeys bodies, have blue color faces. But the fur - a feature common to most terrestrial mammals - is never naturally bright blue color at least, not in visible light.

Blue date

The earliest use of blue color pigment dates back to about 6,000 years ago in Peru, and the ancient Egyptians combined calcium oxide, silica and copper oxide to create a long-lasting blue color pigment to decorate statues.

According to a study published in Frontiers in Plant Science earlier this year, the rarity of blue means that people have viewed it as a high-status color for thousands of years. Blue has long been associated with Hindu Krishna and Lady Mary (peace be upon her) and there are many artists who are famous for their inspiration from the color blue in nature such as Michelangelo, Gauguin, Picasso and Van Gogh.

The rarity of blue in nature may have helped shape our perception of things that appear blue, coloring our human expressions, and appearing in dozens of English idiomatic expressions such as but not limited to ,You can work a blue color collar job.

There are many uses, from describing the difficult days to singing with eyes like blue waves in poetry and singing.
