Acrylic paint is fast-drying paint containing pigment suspended in an acrylic polymer emulsion. Acrylic paints can be diluted with water, but become water-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. Acrylic is generally the one that’s easiest for someone who is new to painting to work with. There are lots of acrylic paint brands and grades. Generally the more expensive paints use more pigment and less fillers. The cheapest acrylic paint is usually the Basics line by Liquitex. Basics brand paints aren’t too bad, although you will really notice the difference if you’ve used higher quality acrylics. Liquitex also has a professional line of paints that go by the name of Heavy Body Acrylic Colors. These are of a better quality than the Basics.
