Part of the explanation is that there isn't a true blue color or pigment in nature, therefore plants and animals must use light tricks to seem blue. The primary reason for this is due to the physics of light. Pigments take on the color of the light that they reflect rather than absorb. This means that if you look at an object that is red then it will still be red even when illuminated by blue lights; only white objects show up as white under such illumination. For the same reason, objects that are blue will still appear blue even when illuminated by red lights.
In addition, most blue colors come from compounds that contain oxygen, and these are found mainly in proteins and chlorophyll (a greenish color produced by plants). Proteins are also where red colors come from, which explains why objects that are red tend to be colored mostly or entirely by protein molecules. Chlorophyll is also responsible for yellow colors that sometimes appear in plants. Animals possess similar chemicals that produce blue colors, but because they're not present in sufficient quantity they usually appear pale or gray.
Finally, there are two types of blue colors in animals: indigo and azure. Indigofera is the name of a genus of flowering plants that contain lots of indigo-colored leaves and flowers. These plants are native to tropical Africa and the Indian subcontinent. Indigo is an ancient dye made from the roots of Indigofera species.
Blue is a prevalent color on the planet. Blue, on the other hand, is extremely rare in nature. Blue flowers are found in less than one out of every ten plants, and even fewer animals are blue. Blue is generated in plants by combining naturally existing pigments in the same way that an artist would combine colors. These combinations usually result from reactions between flavonoids-a type of chemical -in plants. The most common blue pigment is indigo, which gives flowers and vegetables such as broccoli, cabbage, and radishes their color.
In addition to plants, bacteria can produce blue compounds. There are two main types of bacteria that produce blue products: Pseudomonas and Moraxella. Both types of bacteria are found in soil and water and some species of them are useful because they kill other bacteria. When they die, they release these blue compounds into their environment so other organisms can't use them. Nature has done this since early times when there were no people to bother with contaminating environments. Today many industries include steps to remove contaminants before releasing them into the environment. These industries include mining, petroleum refining, and power generation.
There are two kinds of indigo used by plants: Indigotin and Indigo Naturalist. They are very similar except that indigotin is derived from tryptophan and exists only in plants. Indigo naturalist, on the other hand, contains both tryptophan and kynurenine and exists only in animals.
Why is blue so rarely seen in flowers? "Because there is no actual blue pigment in plants, plants do not have a direct technique of producing blue color," Lee explained. "Blue is much more unusual in foliage than it is in flowers," he adds. "Plants adapt or adjust the red anthocyanin pigments to produce blue blooms," Lee explained. "Anthocyanins give flower petals and fruit a pink or red color, but if they aren't used properly by the plant, they can also turn purple or blue."
Actually, most flowers that we see today were not always this way. Before the evolution of modern pesticides, insects would devour many more plants than they eat now. As a result, plants had to protect themselves by emitting toxic chemicals that would make their bodies taste bad enough to discourage consumption. These toxins come in two forms: alkaloids and cyanides. Alkaloids are poisonous because they interfere with the activity of enzymes inside cells-but they can also be therapeutic for people too! Most alkaloids are responsible for the narcotic effects of marijuana, codeine, and morphine. They also play a role in plants' defense systems against pests and predators.
Cyanides are only toxic when ingested-they don't need to be absorbed through your skin or into your system through your lungs.
Despite the fact that blue blooms are uncommon in plants, nearly no plant possesses blue leaves, with the exception of a few species located on the bottom of tropical rainforests. Thus, if more red light is reflected back out into space rather than absorbed, then plants will tend to lose their color and become green or white.
The secondary reason for the lack of blue plants is due to evolution. If natural selection were to favor blue plants over green plants, it would be because they contain genes that give them an advantage over other plants when exposed to high levels of ultraviolet radiation. However, since most of Earth's surface is not exposed to high levels of UV radiation, these genetic advantages would be lost over time.
Finally, there are some rare species of algae that can produce small amounts of pigments that appear blue under certain conditions. However, these are not plants in the normal sense of the word; instead, they are single-cell organisms that belong to a different kingdom (microscopic fungi or bacteria).
Blue Blue is a prevalent color on the planet.
In fact, only two species of mammal, two reptiles, and six fish have been observed to be blue. And although blue whales can reach a length of over 30 feet and weigh nearly 80 tons, they are not alone: also colored red or white are common.
The rarity of natural blue colors appears to stem from the need for their carriers to protect themselves from predators. While red or white are easily seen by birds and other animals, a blue-colored organism would be difficult to detect against its background.
People have used this property of blues for artistic effect since prehistoric times. In caves throughout Europe, Africa, and Asia, you will find drawings and paintings of animals with blue bodies and fur. These include lions, tigers, bears, wolves, and dogs.
In modern times, too, people have exploited the artistry of blues. The Beatles were known for their blue clothes and hair. So was Elvis Presley. Today, many musicians wear clothes and use makeup that reflect a blue color.
Natural occurrences of dark blue are few.
Overall, blue light influences many processes in a plant's life, and it is an important hue to have in your own grow room or grow box to ensure optimal development. The majority of the plants we see around us are green. However, if you were to strip all the yellow and orange fruits and vegetables from the earth, you would be left with only blue and white rocks. Thus, showing that these colors are important for plant growth.
Blue light has two important functions in plants. First, it helps plants to photosynthesize by giving them information about the time of day and year. Second, it signals plants to grow leaves, flowers, and fruit by communicating the amount of sunlight reaching the ground. Without this light, plants would not be able to make any more food than what is absorbed through their roots directly into their cells. This is why plants need exposure to blue light during their early developmental stages to promote strong growth later on.
In addition to being important for photosynthesis, blue light also plays a role in seed germination, stem elongation, and root formation. Research shows that seeds will not always fall into good soil. Sometimes they get stuck in animal droppings or under a tree, and these areas cannot receive enough red light to trigger germination.
