Oil painting is the process of painting with pigments with a medium of drying oil as the binder. Commonly used drying oils include linseed oil, poppy seed oil, walnut oil, and safflower oil.
The choice of oil imparts a range of properties to the oil paint, such as the amount of yellowing or drying time. Certain differences, depending on the oil, are also visible in the sheen of the paints.
An artist might use several different oils in the same painting depending on specific pigments and effects desired. The paints themselves also develop a particular consistency depending on the medium.
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water-soluble, but becomewater-resistant when dry.
Depending on how much the paint is diluted with water, or modified with acrylic gels, media, or pastes, the finished acrylic painting can resemble a watercolor or an oil painting, or have its own unique characteristics not attainable with other media.
Watercolour, also aquarelle (French loanword), a diminutive of the Latin for water, is a painting method in which the paints are made of pigments suspended in a water-based solution. Watercolour refers to both the medium and the resulting artwork.
Watercolor paint consists of four principal ingredients:
pigments, natural or synthetic, mineral or organic
gum arabic as a binder to hold the pigment in suspension and fix the pigment to the painting surface
additives like glycerin, ox gall, honey, and preservatives to alter the viscosity, hiding, durability or colour of the pigment and vehicle mixture
solvent (water), the substance used to thin or dilute the paint for application, which evaporates when the paint hardens or dries
