Q:i also need the color they are links would be great if you know a good one

If you want to physically separate the different pigments, you can use a method called paper chromatography. The chlorophyll is dissolved in a certain solute and is allowed to move through a piece of paper. The different pigments will move at different speeds and they will be separated. But if you simply want to identify the different pigments, you can use another method called spectrophotometry. Different chlorophyll pigments absorb photons of different wavelength. In diethylether, chlorophyll a has approximate absorbance maxima of 430 nm and 662 nm, while chlorophyll b has approximate maxima of 453 nm and 642 nm. So that's how you distinguish between the two.

Q:what are the differences between colorfast and non colorfast pigments?

I'm sure with enough research you will be able to find these answers and explanations in your text book. Or google them, maybe it will have pics to help describe if your more of a hands on learner. Good Luck.

Q:whats it for? lol

itz for ur beautifing ur skin.

Q:do all leaves extract contain the same pigments??why?

Absolutely not. Leaf pigments, just to name a few, may include chlorophyll, carotenes, lutein, anthocyanins. Not only will pigment content vary between plant species, but pigment content will vary in individual plants seasonally.

Q:what is the pigment in hibiscus?

Hibiscus flowers bear pigments of three types: carotenoids, anthocyanins, and flavonols. The exact pigments (all three of those types are actually sizeable families of similar chemicals) and the exact proportions depend on the color of the particular flower: there are literally several hundred species in the genus Hibiscus, and they come in all shades of red, pink, yellow, and orange. Carotenoids are oil-soluble, fairly stable pigments that come in all shades of red, orange, and yellow. Anthocyanins are water-soluble and significantly less stable: they're responsible for the blues, pinks, purples, and reds, and in high concentrations can produce colors so dark as to look black. Flavonols are the least vivid of the pigments: they produce pale pastel yellows, cream colors, and off-whites. (Plain white flowers usually have no visible pigment at all.) Flavonols actually do most of their color absorption in the UV spectrum: they're the plant equivalent of the melanin in human skin, keeping them from getting sunburnt.

Q:I love the colours that pigments come in but I don't know how to use them. Is there any easy way?

You can go to a store that sells makeup and ask them how to use it. They will even show you.

Q:Explain light activation of pigments (absorption of light by pigments)?

A pigment is a substance that imparts color by absorbing some frequencies of visible light but not others. For instance, there are a lot of substances that absorb ultraviolet light into the visible spectrum, in other words they also absorb plain violet light. Since they absorb violet light but reflect back the rest of light, they appear yellow. Purple pigments, on the other hand, are quite rare because they absorb purple light (which has the highest energy of visible light) and reflect back everything else. When anything absorbs a photon of electromagnetic radiation (light, x-rays, ultraviolet, infrared, microwaves, gamma rays, radio waves), it is activated which means that it takes the energy of the photon and goes to an energy state that is higher by the same amount of energy that was in the photon. At the molecular level, energy is quantized, meaning its restricted to particular states. For instance, vibrational energy corresponds to infrared light: there are only certain ways, called modes, that a molecule can vibrate in, if it can't vibrate in an appropriate mode, it can't absorb the infrared radiation that corresponds to being promoted to that mode. That's why substances can be transparent. At the higher energy state, the substance might be able to participate in chemical reactions that it would not be able to participate in in a lower state. That's usually what is meant by light activation. So a pigment that absorbs visible or UV light might become activated and react with something or react in ways that it wouldn't be able to in the dark.

Q:wut is the diff between those 2?

pigments are loose powder i believe. i like the eyeshadows better. there's a much better selection of those anyway.

Q:how exactly do pigments work? i know that they absorb every color except the one that we see, but what are the exact physics or whatever behind the selective absorption of the light?

Different pigments mostly absorb different range at different wavelength of light, but plant -as I know- mostly containing chlorophyll does not absorb green light so we see plants as green.

Q:(After the fifteenth century)

Pigment is color in powder form. An example is lamp black; it was first made from the soot of kerosene lamps ground fine. Binder is a substance used to hold pigment together and make it adhere; in the previous example, linseed oil would be the binder for the lamp black pigment. Vehicle is a medium acting as a solvent, carrier, or binder for paint; turpentine or mineral spirits would be a vehicle but so would linseed oil as well to help dilute the paint and help it cover a large area. Hope that helps and thanx.
