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.
Useful for CBSE, ICSE, NCERT & International Students Grade 12 Subject: Chemistry Lesson :Chemistry in Everyday Life Topic: Dyes Dyes are substances applied in aqueous based solutions to a fabric to give it a colour. What makes a dye different from a pigment is that pigments are usually insoluble. Here in India we have been using methods of dyeing for over 5000 months. Most of the dyes that we know are natural dyes found in the plant kingdom, available from a number of root, berries, bark, leaves and wood.

Original post on our site with additional comments: http://www.thewoodwhisperer.com/videos/you-and-dye/ Its all about dye, "Wood Whisperer Style". My goal with this video is to grossly simplify the confusing world of dyes, while also giving you the knowledge you need to determine the working characteristics of any dye just by looking at the ingredients list or MSDS. We'll discuss the different types of dyes, how to apply them, and we'll even get into the chemistry behind water-based finishes and a key family of solvents known as glycol ethers. Knowledge is power! The Wood Whisperer is education and entertainment for the modern woodworker!

Sasha Duerr uses just about anything to dye clothing: from kitchen waste (coffee grounds, avocado pits and onion skins) to invasive "weeds" (wild fennel, oxalis) to the leaves, fruit or petals of nearly any tree or plant (maple, pear, cherry, fig, acorn, fern, dahlia, poppy, lavender, etc). Inspired by permaculture, Duerr believes in a slower approach to textile dying- she founded the Permacouture Institute to help advance Slow Textiles- both as a way to respect the environment, but also because she believes that plant-based color is more beautiful, and truly alive.

I couldn't find a video on YouTube that side by side compared and gave opinions of hair dye brands, so I thought i'd make my own after using various dyes over the years. I've focussed on ones for the UK market. Hope you enjoy!

Sister love, why don't you break it up?
You got to let someone look into your heart
Sister love, how do you keep it up?
If you don't let no-one look into your heart
As a kid, you couldn't live it up
You were so serious but always so smart
As a kid, you couldn't keep it up
And we were never close, so much apart
Here comes the sun smiling
How long have you been blue?
There'd ever be a time for us to recapture
All the time we lose
There was a time when you were being so proud
Could have been anythin' that you aspired
There was a time when you were never around
When somethin' good happened, somethin' good happened right
So sister love, I'll help you off the ground
You got to let someone look into your heart
You got to turn this situation around
You got to turn this, turn it around
Here comes the sun smiling
How long have you been blue?
There'd ever be a time for us to recapture
All the time we lose
'Cause it's plain to see
A storm is not the weather
And I'm telling you girl
You'll look at them and smile
I'm telling you girl
You'll look at them and smile
7 days you should be givin' yourself
All your belongings, all that you treasure
7 weeks you think of nobody else
Is this what you want, is this what you are?
How did it come this far?
Here comes the sun smilin'
The only thing that's true
There'd ever be a time for us to recapture
All the time we lose
'Cause it's plain to see
A storm is not the weather
And I'm telling you girl
You'll look at them and smile
And I'm telling you girl
You'll look at them and smile
And I'm telling you girl
You'll look at them and smile
And I'm telling you girl
