There are several ways for classification of dyes. It should be noted that each class of dye has a very unique chemistry
A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber.
Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other organic sources such as fungi and lichens.

These dyes are made from synthetic resources such as petroleum by-products and earth minerals. The first human-made organic aniline dye, mauveine, was discovered serendipitously by William Henry Perkin in 1856, the result of a failed attempt at the total synthesis of quinine.
Although shibori and batik techniques were used occasionally in Western fashion before the 1960s, modern psychedelic tie-dying did not become a fad until the late 1960s following the example set by rock stars such as Janis Joplin and John Sebastian (who did his own dyeing).

Perkin named his colour Mauveine, after the French name of non-fast colour which was made of natural dyes. So "Mauve" (a basic dye) was the first synthetic dye stuff. Mauve was a derivative of coal tar.
Synthetic dyes are man-made. These dyes are made from synthetic resources such as petroleum by-products and earth minerals. The first human-made organic aniline dye, mauveine, was discovered serendipitously by William Henry Perkin in 1856, the result of a failed attempt at the total synthesis of quinine.
Dyeing is the process of adding color to textile products like fibers, yarns, and fabrics. Dyeing is normally done in a special solution containing dyes and particular chemical material. After dyeing, dye molecules have uncut chemical bond with fiber molecules.
Direct dyes are defined as anionic dyes with substantivity for cellulosic fibres, normally applied from an aqueous dyebath containing an electrolyte, either sodium chloride (NaCl) or sodium sulfate (Na2SO4).
