Q:i bought mac pro pigments 4 the 1st time , now what do i do?
when you use a pigment, it's always better to apply it wet since it's a loose shadow. with the mixing medium, put a few drops of it on to some kind of surface, like the lid of the jar or even on your hand. if you dropped it in the lid, tap a little shadow into the lid and mix it with your brush. you want a thick, kind of pastey consistency. if your put it on your hand, did your brush into the drops of mixing medium and then then dip the wet brush into the pigment jar. then all you gotta do is apply it to your lid. but make sure you put a base on your lid before applying! good luck! =]
Q:M.A.C pigments question!?
Are you sure they are real mac pigments. Look on the bottom to see if they have names. If not, if they just have a number and not a name, then they are fake and thats probably the cause of the smell. If so, then I don't know. Mine never do. Hope this helps and good luck!

Q:What happens to the yellow pigments in a leaf during the summer months?
in case you may surely ask a query like that, then it sounds to me such as you opt to have intercourse with one in all your instructors. enable me be the 1st to tell you that it will no longer take place! She's/he's have been given a husband/spouse to do each and all the grimy paintings for her/him! you're basically a pupil and that's a criminal offense in each and each state for a instructor to have something for a minor! Have had a weigh down on a instructor, definite that's a load of bull-****, yet that's the way life is and we the two might desire to provide up dreaming and locate ourselves a hoe which will please us in each way conceivable! that's effective to appreciate that somebody else has wandered that. % me as suited answer on account which you and that i've got lots in worry-loose!
Q:mac pigments?
Unlike cheap and nasty makeup there great you only need a tiny bit and it goes so far, vibrant yes there colours are great and come out like there suppose to and stay on for ages, although they can get a bit messy if you'v never used them before, but in saying that use it a few times and you'l get it in no time.
Q:Recommended hair dyes for pre-pigmenting?
once you coloration your hair from blonde back to brown, you will possibly be able to desire to place the 'coloration' back into the hair as while that's bleached, that's stripped of coloration. hence you will possibly be able to desire to place the purple back into your hair. attempt making use of a mahogony coloration which has purple in it. this might forestall that green hue interior the hair. keep in mind, purple fades quicker than the different coloration so as quickly as the purple interior the colour starts to vanish seem boring, you are able to then use a typical brown in case you desire, or shop fresh while needed with the purple/brown. desire this enables.

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:advantages of having accessory pigments?
Each photon has a particular wavelength, determined by the photon's energy. A pigment such as chlorophyll can only absorb photons in particular wavelength bands, matching the energies of available electron transitions to excited states. For chlorophyll, these bands are in blue and red -- the green color of most leaves is due to the waste light that is not absorbed by chlorophyll, while red and blue photons can be absorbed and used to power photosynthesis. An accessory pigment can absorb a photon that has a wavelength (color) outside of the bands that chlorophyll is able to absorb and can pass some of the absorbed energy on to chlorophyll, getting rid of the excess energy in another form, such as heat. A pigment might be tuned to absorb a photon of yellow light; the absorbed energy, stored in the excited state of an electron, is called an exciton (the photon becomes an exciton, so energy is not created or destroyed). The exciton can be passed to a chlorophyll, but only with the same energy as the red photon that the chlorophyll could normally absorb directly. The excess energy, the difference in energy between the yellow and red photon, must be dissipated in another form. This process allows a plant to harvest photons that would otherwise be unavailable to its photosystems. Consider how this would be an advantage to a plant living on a shaded forest floor, or to a planktonic cyanobacteria floating in the water below other photosynthetic algae, in regions where photosynthetically useful photons are scarce.
Pigment is a loose powder that has highly concentrated color. They come in different finishes like matte or shimmery. You can use them as eye shadows and such, which is what most people do with them. They show up better and the metallic ones can be foiled (more vivid color and looks like metal almost) if you use them wet by putting a little bit of mixing medium or eye drops on your brush before dipping it in the pigment and applying it. They can also be used as lip colors by mixing with a clear lipgloss, or eyeliner if you use them wet or mix them with something like MAC's special eyeliner mixing medium. They also make a mascara mixing medium that can be used with pigments. Pigments really are a handy, universal product to have! Keep in mind that some pigments are not safe for use in the eye and/or lip area. If you look at MAC's website where the pigments are, you can check out the specifics about that under View Recommended Use. Also, if you use pigments wet, it's best to get a little bit of it in the jar lid, then dip the brush in it. That way you won't dampen and ruin the pigments in the jar, and moisture in the jar could promote the growth of bacteria.
