Q:What do the pigments in leaves do?
Pigments help in making food for the plants they also give color to it.Pigments are of different types which give different color to its leaves or fruits.Like mango is green first and then turns yellow coz green pigment is replaced by yellow pigment. Green pigment in most of the fruits is present only till it requires food and is raw.
Q:What are MAC pigments?
Eyeshadow I think....
Q:Separation of plant pigments?
Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.
Q:changing eye color/lightening/pigment?!?
Why in heavens name would you want to do this? The best, and safest way is with colored contact lenses. Don't even entertain the idea of surgery. This is your sight! And yes, though we may change the colour of other parts of our body, consider this - how dangerous and abnormal it is to do so! You probably have very beautiful eyes and don't realize it.
Q:How are plant pigments involved in photosynthesis?
Plant pigments - as other pigments - interact with light to absorb only certain wavelengths. In plants the different sorts of pigments are useful to absorb available wavelengths of light and enable photosynthesis in shadow, in bright sunshine, in deep sea etc.: each pigment reacts with only a narrow range of the spectrum, there is usually a need to produce several kinds of pigments, each of a different color, to capture as much as possible of the sun's energy.
Q:what is the function of plants pigment?
plant pigments are of types---- LUCOPLAST- colourless, found in roots, collect food.,,, CROMOPLAST-- Of difrent colour (not green), in flowers atract insect for polination, in fruits atract animals for seed dispers,,,,CLOROPLAST-- Convert light energy to chemical energy, in leaves and otner parts....
Q:Bright Eye Shadow Pigment?
(they are not all palettes that you'd be wanting, but it will give you a good idea of what is available) Otherwise, there are brands like Kryolan and Ben Nye that sell palettes for much cheaper and that have really nice colours (in fact, I remember seeing a MAC promo with behind the scenes pictures, and the makeup artist is actually using the Ben Nye palette to create the makeup look) I think you can only buy these online, but there are MANY websites that well these. I personally would suggest getting your makeup in person though, because you never know what the makeup will look like or how it will react unless you see it in person.
Q:what looks good with mac melon pigment?
With the Melon pigment, I would recommend using warm, chocolate copper, bronze types of colors. It will provide a nice contrast to the melon while giving your eyes some added depth and definition. As far as brushes go, I like using the 252, large shader brush. This brush picks up pigment nicely and it has nice compressed/dense bristles so you can manipulate and lay the pigment down with greater ease. I like the #286 The dual fiber blending brush for pigments as well. It's made of natural fiber and synthetic fiber. This is a great brush because you really get 2 brushes in 1. With this 'blending' brush you can also use it for targeted color deposits and the synthetic fibers won't suck up what you just laid down and you will get a flawless, beautifully blended eyeshadow application.
Q:What are the ingredients in MAC's pigments? (10pts)?
Mac Pigment Ingredients
Q:What eyeshadow brand is the most pigmented?
MAC's eyeshadows are very pigmented, definitely worth the money. They have packed eyeshadows and loose pigments and both are extremely pigmented. I'm sorry for using the word pigmented so much. XD You could also get Urban Decay eyeshadows, those are pigmented as well, but they're usually more expensive than MAC eyeshadows.
