Dye is used to change the color of things, like cloth. A pigment is like the color and texture of your skin. Or the color in paint.

Q:is it the ink on regular printers?

Some printers use only pigmented ink. Others use dye based and then some use a combination of both. Dye based ink is basically water based with a dye added to it. Pigmented ink has a solvent base with dye added. Pigment ink and dye based ink have both advantages and disadvantages. Dye based ink have better colors but pigment are more water and fade resistant. Dye based inks are therefore better for photos. I have a printer that has 4 dye based inks and a black pigment ink. Mine uses the dye based black and colours for pictures and the pigmented black is used for text. So the answer is yes. Pigmented ink is used in some regular printers.

Q:do all leaves extract contain the same pigments??why?

Absolutely not. Leaf pigments, just to name a few, may include chlorophyll, carotenes, lutein, anthocyanins. Not only will pigment content vary between plant species, but pigment content will vary in individual plants seasonally.

Q:If they are not the same, then what is the difference? Please help me out here.

Yes, tannins are pigments but they aren't really the main plant pigment. Plant pigments usually refer to photosynthetic pigments (chlorophyll, carotenoids, etc.). These photosynthetic pigments give the leaves their green color (or yellow/orange in the fall). Tannins are non-photosynthetic phytochemical (involved in plant metabolism and internal functioning), but they are also a pigment. Tannins (and lignins) are brown. This is was gives dead leaves and wood their color. Tannins also leach out of the leaves when soaked in water (same process as brewing a cup of tea). So tannins are pigments when they leach out of leaves and stain water (or other things) brown, but they are not photosynthetic plant pigments. In other words, it depends on what context you are calling a tannin a pigment. In a live plant they are not a pigment (judgment call here). In a dead leaf or when they leach out of a leaf they are a pigment.

Q: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.
