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.
Both dyes and pigments are colored because they absorb some wavelengths of light more than others. In contrast to dyes, pigments are insoluble and have no affinity for the substrate. Some dyes can be precipitated with an inert salt to produce a lake pigment, and based on the salt used they could be aluminum lake, calcium lake or barium lake pigments.They are of many types as we know that indigo is a type of plant which was rashly cultivated in bangal by the Britishers as to make different color of dye.
The majority of natural dyes are from plant sources: roots, berries, bark, leaves, and wood, fungi, and lichens. Textile dyeing dates back to the Neolithic period. Throughout history, people have dyed their textiles using common, locally available materials. Scarce dyestuffs that produced brilliant and permanent colors such as the natural invertebrate dyes Tyrian purple and crimson kermes were highly prized luxury items in the ancient and medieval world. Plant-based dyes such as woad, indigo, saffron, and madder were raised commercially and were important trade goods in the economies of Asia and Europe. Across Asia and Africa, patterned fabrics were produced using resist dyeing techniques to control the absorption of color in piece-dyed cloth. Dyes from the New World such as cochineal and logwood were brought to Europe by the Spanish treasure fleets, and the dyestuffs of Europe were carried by colonists to America.
The walls so high and you won't feel
The moon is always spying on your fears
I make it to the golden geek and fail
So then you throw your fantasy away to fade
Oh and I take
Take it in vain
So I fake
Fake it again
To Tokyo network stocks I stream
All of my wasted dreams on the screen
Oh and I take
Take it in vain
So I fake
Fake it again
Couldn't I
Not take in pain
Couldn't I
Not fake it again
Can't I not take in pain
Can't I not fake it again
I've sent my heart away
