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 requires a mordant to improve the fastness of the dye on the fiber.
Both dyes and pigments appear to be colored because they absorb some wavelengths of light more than others. In contrast with a dye, a pigment generally is insoluble, and has 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.
Dyed flax fibers have been found in the Republic of Georgia dated back in a prehistoric cave to 36,000 BP.Archaeological evidence shows that, particularly in India and Phoenicia, dyeing has been widely carried out for over 5,000 years. The dyes were obtained from animal, vegetable or mineral origin, with no or very little processing. By far the greatest source of dyes has been from the plant kingdom, notably roots, berries, bark, leaves and wood, but only a few have ever been used on a commercial scale.
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
