Throughout my life I have believed that colors in our lives are known and counted and have effects to varying degrees between light and dark, then I recently discovered that I was wrong, and that colors do not have a ceiling. There are always new colors that enter our lives and invented and registered and officially patented to prevent others from using them.
Over tens of thousands of years ago, man created colors through simple chemistry using natural materials such as fruits, charcoal and chalk, and the use of color was limited to giving a certain luster to a piece of cloth or drawing in a temple or the color of a vehicle or drawing a painting, but in recent years science has found uses of new colors, for example, tanks need a special paint that makes them difficult to see. Also, mirrors in various uses need to be brighter, and missiles and satellites need colors that reflect or absorb light and are able to go deeper into space.
Today, researchers are using physics to create new colors as a result of an interaction between light and blue nanoscale features that are much thinner than a human hair.
Historically, saturated colors had a great symbolic power in humans, in addition to the color association with the human soul, rituals and beliefs, even superstitious ones.
Despite the association of color with human life and traditions, such as brides wearing white clothes, or wearing black at funerals, there are many people who do not agree with this general impression, but rather do the exact opposite.
Colors have general meanings. The red color, for example, contains symbols such as health, vitality, war, courage, anger, love and religious enthusiasm, all of which mean a passion for life because the color is associated with blood.
For some, the white color symbolizes purity and serenity, and it is worn at weddings and when performing religious rituals among Muslims and Christians.
The black color is the color of mystery and wisdom, perhaps because of its association with darkness, and the absence of human awareness, and thus it became in other cultures the color of the robes of mourners, and even the dead.
Purple symbolizes family nobility and aristocratic roots, and ancient regimes prohibited the public’s use of this color. It is also a very difficult color to produce. The blue is the color of a clear and calm sky, but in many cultures it expresses sadness and despair. The green color symbolizes nature and the environment; and sometimes wisdom. It is the color of spirits and angels. It also has another aspect in its degraded meaning, which symbolizes a green-eyed monster, jealousy and everything that portends death.
The yellow color, which is preferred by Queen Elizabeth, for example, is the color of happiness and warmth because it is associated with the sun’s rays in the cultures of cold countries. In other cultures, such as the ancient Egyptian and Chinese, yellow was associated with nobility and the dress of religious figures and members of the royal family from the gods. Since all colors have their other side, yellow also represents cowardice and deceit. Orange was not important in ancient civilizations, but recently it is used to sound a warning, like the colors of plastic cones that are placed on the roads and used on safety clothing and equipment.
Scientists recently developed a white coating that reflects more than 98% of sunlight, which makes it effective in cooling buildings, cars and warehouses with steel roofs, and greatly reduces the need for air conditioning inside.
