Dye and pigments
The primary application of Dyes and pigments is to provide colour to materials, whether they are textiles or paints.
While dyes are soluble in mediums like water, pigments a must be converted to a coarser powder after which it is mixed with a dispersing agent

before application.
The difference between the nature of dyes and pigments leads to vastly different uses. On one hand, dyes are mainly used in the textile and paper market whereas pigments find applications in industries like colouring paints, inks, cosmetics, and plastics.

While the application of both dyes and pigments is to give colours to materials, both of them differ widely in terms of the materials they can be applied to as well as the way they function. Dyes can be used with a dye solution (dyes dissolved in water) as well as directly,

depending on the chemical composition of the dye and the material being dyed. Thus, it is an important part of any dyeing process is to find a material onto which the dye can attach itself.

A pigment cannot be directly applied to a material. It must be done with at least two parts, although usually more are used, commonly known as the pigment and the vehicle. The third part usually used is called Thinner. Each of the component involved has a distinct function.

A vehicle is responsible for carrying the pigment to the surface whereas a thinner would be used if the vehicle is too viscous, and therefore difficult to apply on the surface. Once a mixture of these three is applied, the thinner quickly evaporates and what remains evenly spread

On surface .

Dyes are usually water soluble- used for coloring textiles, paper and other substances while pigments are used for coloring paints, inks, cosmetics and plastics.
