Colors
Colors are among the main and important elements that support the visual and plastic arts, which have attracted the attention of artists and researchers at the same time. Where they were confused about the reason why a chemical compound distinguishes and gives the characteristic to an element, while another compound produces a different color and another recipe that calls the same compound if used with it, and they wondered how the human eye sees and distinguishes these dyes, in addition to linking light and its effect on it as well, and based on These extensive experiences classified colors within what is known as the color wheel of several types, and their manufacture increased and became more widespread and developed in our current era, and the method of their manufacture will be clarified in the coming paragraphs.
How to create colours
The method of making colors differed in antiquity and advanced in our current era, through the following methods:
The ancient way of making colors
From the past until the nineteenth century AD, the colored dyes that were used to make colors were of natural origin, so man extracted them from plants, their fruits or roots, or from insects and minerals of various kinds
but the problem was the expensive cost of extraction, manufacturing and production, and with the progress of time and in 1956 A chemical scientist accidentally discovered an industrial dye during a special experiment with malaria on coal tar, which resulted in the violet color, which he later tested and dyed on silk fabric and presented as a new invention of colours.
Different colors that helped produce colors, and at the same time supported some inventions and experiments in the field of photography, plastic industry, modern medicine, and others.
The method of making colors in the current era
It was mentioned before the beginning of the extraction and manufacture of chemical dyes, which caused a great and widespread uproar in the field of colors and paved the way for work on them, as chemical scientific experiments were carried out by various scientists to extract dyes in other new colors, which relied on interaction with coal tar as well, which in turn succeeded, and it was established Accordingly, several factories dedicated to producing it in different countries
where many colors were manufactured at a much lower cost than the primary methods of extraction, which relied on natural materials and elements, in addition to their entry into the field of medicine as well, where dyes entered the experiment of killing bacteria through colored microscopic slides that Doctors used it for this purpose, to prove its success efficiently, and here it was used in turn to manufacture antibiotics and medical drugs, which brought about another revolution in the field of manufacturing and using these colors and increasing the chances of benefiting from them in textiles, medicine, and coloring the plastic industries, and other products that are famous in the present time
