Q: What is the difference between dyes and pigments? Could you give some examples of each one please.: nan

Q: Can some one suggest chemical pigments that can be easily made from chemicals available in a chemistry lab for a project?I need the name of the pigment, reactants required and chemical equations of reactions involved.I need atleast 5 pigments: Typical pigments: carbon black (charcoal) titanium dioxide red iron oxide white lead cadmium red cadmium orange cadmium yellow

Q: which do you think is better??? and how do you apply pigment??? my boyfriend gave me a bag full of MAC make up in which there are 2 pigment bottles... i already love their eyeshadow.. i just want people's opinion on which one is better and when to use pigment... i mean, what is the difference??? Help Please!: Pigment gives a stronger color. You can apply it normally like shadow with a brush or put water on the brush and apply it to intensify the color. I like pigment for a night time look and shadow in the evening.

Q: explain an absorption spectrum of different pigments and the action spectrum ofphotosynthesis.: A pigment is any substance that absorbs light. The color of the pigment comes from the wavelengths of light reflected (in other words, those not absorbed). Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes. Black pigments absorb all of the wavelengths that strike them. White pigments/lighter colors reflect all or almost all of the energy striking them. Pigments have their own characteristic absorption spectra. The action spectrum of photosynthesis is the relative effectiveness of different wavelengths of light at generating electrons. If a pigment absorbs light energy, one of three things will occur. Energy is dissipated as heat. The energy may be emitted immediately as a longer wavelength, a phenomenon known as fluorescence. Energy may trigger a chemical reaction, as in photosynthesis. Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane (as in a chloroplast) www.emc.maricopa.edu/faculty/fara...

Q: What is the role of pigment in photosynthesis photosynthesis ?: The pigment is known as chlrophyll, and plays a vital role in photosynthesis. It is a principal light-capturing pigment in most plants, algae and cyanobacteria. In plants and algae, chlorophyll is located in the thylakoid membranes of choroplasts. During the reaction of photosynthesis carbon dioxide and water produce energy using light energy trapped by the green pigment chlorophyll. This reactions primary products are ATP and NADPH, with oxygen being produced as a waste product. Photosynthesis takes place in the chloroplasts, where the green chlorophyll pigment is located.

Q: Explain why plants need a variety of pigments to carry out photosynthesis?: It is particularly obvious in seaweeds. The pigment employed by the plant will vary according to the light available, so that seaweeds in shallow water tend to be green but those from deeper water are brown and then, where light levels are really low, seaweeds are red. In most of these cases photosynthesis is still carried out by chlorophyll but the associated pigments help with the absorption of the available light.

Q: What are iridescent magnetic effect pigments?: Iridescent okorder /... (really long explanation)

Q: what is pigment?: a pigment has some kinds like biological pigment and arsenic pigment. i dont know much about the arsenic pigment. i would just tell something about the biological pigment. in biology, pigment is any material resulting in color of plants or animals cells. many biological structures like eyes,fur,hair and skin contains pigments like melanin in specialized cells called chromatophores.

Q: I have dyed my hair dark brown for months now it keeps fading because i've had bleach on before hand, so I need some advice on buying decent hair dyes for pre-pigmenting it so my hair dye stops fading out into a horrible gingery brown!: Pre Pigmenting Will Help Prevent Fading But, You Said Your Hair Had Been Bleached Before. So, You May Need Some DEEP Protien Reconditioning Too. Start By Using A Good Protien Treatment After Every Shampoo. Then, Use A Color Treatment Like ARCtec (Found In Salons And Beauty Supplies) This Will Build-Up The Hair's Pigment Levels. There Are Also Pre-Color Treatments Like L'OREAL Pre-Color Primer, That Will Help Color To Take More Evenly And Last Much Longer. Also, Try MATRIX ForteThérapie Cera-Repair. It Contains Ceramides, Which Are The Glue That Hold Hair And Skin Cells Together. With The Internal Structure And Surface Cells On The Hair (The Cuticle) Reinforced, Your Color WILL Last Longer.

Q: We see pigments everywhere in products. They make a variety of things we see today. Where does it come from? Do they actually take a red rose pedal, grind the color and designate it as the color red?: Color is made from a variety of methods.
