acrylic colors definition

Acrylic colors are created by spreading out pigments in a transport made from a polymethyl methacrylate solution mixed in mineral spirits.  They are different from polymer colors (containing acrylic and other resins mixed in water) and may be referred to as plastic paints or straight acrylic colors to differentiate between them.  Acrylic colors can be easily taken off with turpentine and mineral spirits; moreover, they dry fast and do not yellow over time.  Because of these characteristics, acrylic colors are good for inpainting in order to repair damaged or destroyed parts in conservation work.
