What is color in the textile:


People have been able to recognize color from nature. Nature’s various trees, flowers, fruits, leaves, cloudless skies, etc. have not only overwhelmed people but also taught them different names for colors. Therefore, from time immemorial, the effect of color on human feeling has been obvious and extensive. All human beings, from infants to adults, have different dimensions of color. Clothing plays an important role in enhancing the beauty of a person. So in these cases and the diversity of human preferences is wider.

As soon as people get into the habit of wearing clothes, the idea of ​​dyeing clothes with colors is probably the origin of the stains of different natural colors on the clothes.

The first letter of color in English is synonymous with color and in the second case, it can be synonymous with dye or pigment. Color is the effect of the appearance of a certain range of wavelength, which is reflected from an object and is reflected in the human eye to create a certain feeling. It is a kind of light energy. It cannot be touched, that is, it is abstract.

The definition of color in the book “Textile Terms and Definitions”, published by the British Textile Institute and edited by Prof. McIntyre, is as follows: The appearance of color to a human being is a psychological real response caused by his feelings and psychological reactions to the senses.

Here are all the features that enable the eye and the brain to distinguish between the qualitative aspects of color. It is very easy to say when an object is colored in a certain way see that the external color of the object is its color, that is, if an object is blue with our eyes, then the color of that object is blue.

What is color in the textile-The regulating factors of color:

The color of an object that we see with our own eyes is the combined result of the properties of three things.

(A) Internal and external properties of the object such as the physical aspect of the object, its density, shape, and behavior of the object towards the object, etc.

(B) Characteristics of the light in which the object is being scattered or in the light which is being refracted through the object or in the light in which the color is being reflected from the object.

(C) Our eyes, where the light coming from the object is being reflected/reflected, i.e. the regulators of color vision, the absence of any one of the objects and the eye means the non-existence of color. And if the properties of the three controllers are more or less compatible, it will play a proportional role in changing the appearance of the color. To understand what color is and how it is visible, it is necessary to have a minimal idea about the characteristics of each of the above-mentioned elements, their role, and their interaction/reaction and coordination.

What is color in the textile-The Substance of the source of color:

Chromophorous is a type of unsaturated chemical organic compound or group such as azo group (- N = N -) or various similar groups, due to the presence of which a part of the visible light is absorbed. Chromophores are two Greek words. Such chrome means color. And consists of a combination means carriers. The compound that carries chromophores is called chromogen.

Because of the relatively unsaturated state of the chromatophores, only a certain range of electromagnetic waves are absorbed and distorted, so only a fraction of the visible value can be absorbed or reflected by a chromagen-containing substance. The chemical signals of some of the chromophore groups present in the dyestuff are azo group (-N = N -), nitro group-NO, carbonyl group> C = 0, etc.

Since chromagen compounds cannot be added to textile fibers or fabrics alone, it is not possible to dye textile products with such compounds. Only when auxochrome is combined with chromagen can it become pigmented. Oxochrome is a chemical group of amines (Amino-NH) which, when combined with azo or nitrous (-N = O) group, can dye textile products and produce effective dyes. Some of the oxochrome groups are Amina-NH, Carboxyl group-COOH, Sulfone group-SOH, etc.

The Greek word auxin means growth and the combination of chrome (meaning color) gives rise to auxochrome. The presence of oxochrome affects the loose or unstable electronics orbit of unsaturated chromophore bonds and enables the corresponding compound to absorb and reflect at a range of wavelengths. So the molecule of the dye must have oxochrome along with chromophore. Moreover, the molecule shape of the dye must be such that it can easily penetrate the inside of the fiber.


 Lights role is very important in making the color visible. For a colored object to be visible, it must be reflected in the light and reach the eye. Recognized as a form of energy in physics. And it is the radiating energy or part of an electromagnetic spectrum.

Light may have originated from different sources. Such as sun, gas, kerosene, petrol, wood, etc. from fire or bulbs ignited by electric energy.


Sunlight is a type of radiating energy that reaches the earth with the help of electromagnetic waves. The amplitude of this wavelength is very wide. Ultraviolet-visible light or visible light infra-red, radio wave to wave gradually increases. These are visible to the human eye with a wave spectrum of 350 nanometers (nm) to 700 nanometers, which we refer to as the visible spectrum. People do not see any lights above or below this wave range.

Note that as the wavelength increases from purple to part of the visible light spectrum, the clusters of colors take on the form of Indigo, Blue, Green, Yellow, Orange, and Red.
