Q:What is color and how are pigments made?
Pigments selectively reflect and absorb specific wavelengths in the visible region of the electromagnetic spectrum, which is roughly between 400 and 800 nm wavelength. When visible light is incident on a pigment parts of the spectrum are absorbed by certain chemical bonds that are found in conjugated systems or other components of the pigment, known as chromophores or colour centres. Other wavelengths or parts of the spectrum are reflected or scattered. Many pigments are charge-transfer complexes, such as transition metal compounds, but there are others that are organometallic compounds. These have wide light absorption bands that subtract most of the colours of the incident white light. The resulting reflected light spectrum creates the appearance of a colour. The difference between a pigment and a dye is that a pigment is insoluble in the substance that it is used to colour, therfore what you actually end up with is a suspension (e.g. blue pigment in polyethylene), whereas a dye soluble in a carrier so you end up with a solution of the dye, and the solvated dye molecules have an affinity to the surface of the substance that they are being used to colour (fabric dye molecules adsorb to the surfaces of the fibres that make up the fabric).
Q:Plant Pigments And Biology?
Pigments in the reaction center work together to organize themselves in place, to protect the plant from injury from incidental light, and to absorb photons from the spectrum with each pigment catching its own portion of the incoming wavelengths. The accessory pigments catch and pass energy to chlorophyll a. Chlorophyll a is the specialist that plays the photon's electromagnetic energy into chemical. It splits water to release its electrons and hydrogen ions for use in the calvin cycle where glucose is manufactured. The goal is to fix energy into a usable organic form for the plant to live on.
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:Is gel food coloring a pigment or a dye?
Dyes contain pigments, my friend. What is a pigment? They are like little beads. Very very tiny beads of the same color. Then if you spread these out, they give the thing a color. For example, the little green beads in leaves give it a green color. Pigment in our hair gives it a blonde/auburn/brown/black color. What is a dye? A dye is a liquid made up of water and pigments. The pigments are dissolved in water (well not really dissolve just that you cant see the beads) so that it's easier for us to use it. Everything that has a color is made up of pigments. So, gel food coloring is a thicker version of a dye that contains pigments.
Q:What is the difference between a pigmented eyeshadow and a non - pigmented one?
Pigment is the amount of saturated color that will come up when you touch the eye-shadow with your finger (or apply it with a brush) A poorly pigmented dark purple eye shadow may leave only a soft wash of sheer lavender pigment on the eye, and it may require you to apply several layers to achieve a color similar to how the shadow looks in the pan. A highly pigmented shadow has great color payoff, and looks (on the eyes) the same as it does in the pan, and doesn't require lots of packing on the color. Highly pigmented eye shadows are preferred by most people because they are quicker, and easier to work with and stand out. Poorly pigmented eye shadows, however, may be great for younger girls who are just starting to wear makeup, girls with very fair skin, or people who like Subtle makeup An example of poorly pigmented eye-shadow would be the Color Workshop palettes often sold at drugstores around Christmas, they are fine for beginners, but for people who want dramatic makeup they will not be able to achieve the look with shadows of this quality. Wet n wild 3 pan palettes, and most of the 8 pan palettes are very pigmented, as are L'Oreal infallable eyeshadow-pots, MAC eyeshadows, urban decay eye-shadows and most of the higher end shadow brands. Some eye-shadows targeted towards older women, such as Elizabeth Arden, although pricey, lack pigmentation.
Q:Can someone describe the role of accessory pigments in photosynthesis?
Accessory pigments help the plant absorb energy from different wavelengths of light other than those that are absorbed by the main pigment chlorophyl.
Q:Why do algae contain pigments other than just chlorophyll?
they stay underwater...the water swollows easy in a definite sequence, so the deeper they stay the greater distinctive is the easy and that they elect different pigments than landplants.
Q:Can MAC pigments be used as regular eyeshadows? They seem to all be glittery...?
Of course they can ! I love mac pigments. Yes, fallout is involved..but what i do is i use my mixing medium with them so that they go on wet and no fallout. If you don't have mixing medium you can mix them with eyedrops. What i do is i put a drop in the lid and pick up some pigment and mix it till i get the perfect consistancy. You can also learn how to press them, so that they can become pressed eyeshadows instead of loose. But if you just want to use them loose, make sure you get a good flat shader brush...make sure you pat the pigment on your lids insted of in a swiping motion, this also prevents less fall out. Get some loose transparent powder as well set that under your eyes, and swipe it off when done..this makes the fallout swipe away without smearing on your face.. Hope that helps ! If you want you can do all of this, but you don't have to...just random tips to prevent that annoying fallout
Q:thinking about the main role of pigments in photosynthesis...?
Green pigments absorb light in the red and blue parts of the spectrum and reflect the green back to our eyes. The major functional difference between chlorophyll and say jade green is that only the chlorophyll in living systems can transfer the absorbed light energy and the excited electron to another molecule, thus trapping it. In biology, pigment is any material resulting in color in plant or animal cells which is the result of selective absorption. Some biological material has so-called structural color, which is the result of selective reflection or iridescence, usually done with multilayer structures. Unlike structural color, pigment color is the same for all viewing angles. Nearly all types of cells, such as skin, eyes, fur and hair contain pigment. Butterfly wings typically contain structural color, although many of them contain pigment as well. Creatures that have deficient pigmentation are called albinos. In the coloring of paint, ink, plastic, fabric and other material, a pigment is a dry colorant, usually an insoluble powder. There are both natural and synthetic pigments, both organic and inorganic ones. Pigments work by selectively absorbing some parts of the visible spectrum (see light) whilst reflecting others. A distinction is usually made between a pigment, which is insoluble, and a dye, which is either a liquid, or is soluble. There is no well-defined dividing line between pigments and dyes, however, and some coloring agents are used as both pigments and dyes. In some cases, a pigment will be made by precipitating a soluble dye with a metallic salt. The resulting pigment is called a lake.
Q:changing eye color/lightening/pigment?!?
Whatever you decide to do...just remember that you ONLY have two eyes, you mess up with your vision and the consequences are not good..you can seriously hurt your vision and even become blind for life.. Just be happy with what you have and wear contacts to change your eye colour.
