pigments means colour
▪️colored material that is completely or nearly insoluble in water. ... Generally dyes are often organic compounds whereas pigments are often inorganic compounds. Pigments of prehistoric and historic value include ocher, charcoal, and lapis lazuli.
▪️Pigment, any of a group of compounds that are intensely coloured and are used to colour other materials.
▪️Chlorophyll, which gives a green color to plants, and hemoglobin, which gives blood its red color, are examples of pigments. A substance or material used as coloring. (biology) Any color in plant or animal cells. Chlorophyll is the pigment responsible for most plants' green colouring.
▪️Pigments are used for artists' paints, car finishes, and light-reflecting signs. They are insoluble materials that have to be mixed with binders or vehicles to attach them to a substrate. Pigments are often derived from minerals, but they can also be made synthetically.
▪️natural pigment is one that is found in nature that is ground, sifted, washed, and in rarer cases, heated to create a desired hue. ... Artists used whatever pigment was available to them through natural resources. This included earth pigments such as red and yellow ochre, charcoal, and white from ground
▪️Plant pigments include many molecules, such as porphyrins, carotenoids, anthocyanins and betalains. All biological pigments selectively absorb certain wavelengths of light while reflecting others.

▪️three
There are three basic classes of pigments. Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate.
▪️anthocyanins and other flavonoids, betalains, and chlorophylls. Chlorophylls, which are green, and carotenoids, which are yellow, orange or red, play pivotal roles in
▪️Most pigments work by absorbing certain wavelengths of light. Other wavelengths are reflected or scattered, which cause you to see those colours. At the atomic level, certain wavelengths of light are of the correct energy to excite specific transitions of electrons in the molecules or the solid.
