Watercolor is a transparent medium made from refined water-soluble pigments, available in both pan and tube form. It is highly suitable for subtle renderings on paper and board. Oil color is mixed with linseed oil and dries very slowly. It is usually used on primed slightly absorbent surfaces such as canvas, board and masonite. Acrylic paint represents a technological advance in the formulation of artist’s color. It is a quick drying synthetic plastic emulsion, which behaves both like watercolor and oil paints as it is capable of thinned application for wash effects and can be used for thick impasto techniques.
Spray Cans of Paint and Acrylic Spray Paint are used for all types of techniques and gradients, they provide precision and high quality color for professional quality art. Encaustic Wax Paint can be used in many diverse ways creating texture and unique painting qualities. Airbrushing is another style of painting offering a wide array of techniques to painting beautiful realism and gradient. Different Palettes work better for different paints.
Paints are the combination of coloring material and finely ground pigment, mixed to a smooth consistency with a binder. The pigments themselves can be broadly classified as either organic (derived from living organisms) or inorganic (minerals).
Pigments Inorganic pigments are of mineral origin, some of which include raw umber, ochre, burnt umber and burnt sienna. Artificially prepared mineral colors include cadmium yellow, zinc oxide, etc. Organic pigments are of animal, vegetable or synthetic origin and include indigo, madder, Indian yellow, etc. Synthetic organic pigments such as cerulean blue, cobalt green and cobalt yellow are characterized by great brilliance and intensity and should not be thought of as inferior to their natural counterparts.
Because of the many variable conditions both in nature and in the manufacturing process, many qualities of pigments exist. Most paints are sold in artist and student grade. Artist quality paints contain the best pigments. Student colors generally contain the cheaper pigments, and are coarser in texture. Hue is another way of classifying a paint. Often substitute pigments are used in student grade colors to reduce cost and are hence labeled “hue.” Sometimes the original colors no longer exist, such as with Indian yellow hue, or original pigments are found to be poisonous and are substituted as in the case of Naples yellow hue.
Binders Each type of paint has a different binder that mixes with a pigment to create a smooth consistency. For example, linseed oil is the binder used for oil paint, gum arabic binder for watercolors and acrylic emulsion is the binder for acrylics.
