In photosynthesis whats the difference between primary and accesory pigments?
yesterday
I am planning on purchasing MAC, but what r the differences... thanks to all...I want to have an idea before I head to the mall.
Pigment is the purest formula or color with minimal ingredients mixed in to buffer or thin out the product. Generally, the loose form is the most intense because it is lightweight and you can pack it on, mix with a medium, or layer. Pigments usually cost more than pressed forms. However, there are some pressed pigment shadows that are awesome (NARS, Make up for Ever, Urban Decay)! MAC has excellent shadows, I use a lot of them (loose pressed) in my kit. Loose pigments are great mixed with water or mixing medium to intensify. They also will last you forever!
I need to know the classes and sub classes of pigments classification
organic pigment and inorganic pigment
I have been looking over the internet and have yet to find the details I need. Such as the function and development of Pigments.
any of a group of compounds that are intensely coloured and are used to colour other materials.Pigments are insoluble and are applied not as solutions but as finely ground solid particles mixed with a liquid. In general, the same pigments are employed in oil- and water-based paints, printing inks, and plastics. Pigments may be organic (i.e., contain carbon) or inorganic. …
My wife went to the eye doctor to get new glasses (because she couldn't renew her driver's license with her glasses she had been using), and the doctor said that she wasquot;losing pigment" in both of her eyes. He said not to worry, but he wants her to make an appointment every 6 months, instead of just once a year.What does it (her losing pigment in her eyes) mean? Is it really nothing to worry about?(My wife doesn't seem worried, she hates going to doctor's but she trusts them when she goes to them; she doesn't ask questions-- she feels that if she needed to know something the doctor would tell her.)
I'm going thru the same thing, I have been to see my eye dr every 6 months to find out about pigment loss and I am losing my pigment at a fast rate 4 times worse than 6 mths ago. they are calling in the specialists about it, so YES worry!!!
i need pigment in powdered form and i need it to be oil based for my resin project. i was thinking about just crushing up artist oil pastels but i need it to be really fine with no chunks. sooo, i was wondering if anyone sells really fine oil based art pigment powders in a variety of colors. or do you know of i way i could crush up the pastels super fine so it will mix evenly into the resin? (i hope this made sence, i don't know much about art lol)thanks!!!:)
Hi. okorder /... Those are all pure pigments, no hues or imitations. The prices may seem high, but even a half a pound of pigment is a huge amount. Prices I've seen on other sites are higher. I do not think it will work to crush up pastels, oil or otherwise, because they already have a binder and probably a lot of filler in them -- you will get a very weak color. Hope this helps.
i was thinking of this all day long and then i thought of posting this question for you to help me sort it out
Pigments are chemicals inside living things that absorb certain types of light. In plants, the pigment chlorophyll in leaves absorbs sunlight for photosynthesis to work, where the energy comes from. Chlorophyll absorbs all light except green, which is reflected. That's why most plants are green. NOT the other war around. :) :)
Know this ounds kinda obvious but just wanted to confirm, is there more pigment in the middle of the beetroot than on the edges?
I've known it to be in the skin and thats from a cooking point of view.
