In view of the immense blue sky or the ocean, one might think that the color blue is super common in nature. However, of all the shades present in rocks, flowers, plants, feathers and animal scales, blue is the least observed color.
Science has found the explanation for this question and we will share with you in this article the answer to the question: Why are there so few blue things in nature? Check out!

After observing how unusual the color blue is in nature, a German journalist named Kai Kupferschmidt wrote a book about it, whose title is “Blue: In search of nature’s rarest color”, which can be translated as “Azul: in search of the rarest color of nature”.
In the case of flowers and vegetables in general, when we see blue, it is because of the relationship between the way the information from the reflected light is emitted and interpreted by our brain.
In summary, for a flower to be blue it needs a molecule that is capable of absorbing the red part of the light spectrum. That is, it means saying that a flower is blue because that is the part of the light spectrum that it “rejected”.
Regarding animals, the pigments they exhibit in their fur, feathers or skin have a direct influence on their body structure. For example: butterflies with blue wings belonging to the genus Morpho have nanostructures in some layers of their wings that manipulate light and reflect only blue.
In addition to butterflies, a similar effect exists in structures present in the feathers of blue jays and also in the bright rings of poisonous blue-ringed octopuses. Thus, the blue plumage of birds such as the hyacinth macaw gets its color from structures in the feathers that can scatter light.
A curiosity is that shades of blue are even rarer in mammals than in birds, fish, reptiles and insects. In this sense, only some whales and dolphins have some part of their skin bluish; as well as mandrills (Mandrillus sphinx) and golden snub-nosed monkeys (Rhinopithecus roxellana).
The rarity of blue has earned this color high status for thousands of years. Blue has long been associated with the Hindu deity Krishna. In addition, blue served to inspire very famous artists such as Michelangelo, Picasso, Gauguin and Van Gogh.
