As acrylic paints began to become more widely available, companies began making acrylic paints that were formulated specifically for figure painting, characterized by being thinner than artist acrylic paints, with more flow, and having higher pigment density and more finely ground pigment than cheaper craft acrylics. These include companies that only make paints and paint related products, such as Acrylicos Vallejo's "Model Color" and "Game Color" lines, companies that make paints to supplement gaming model lines, such as Games Workshop's "Citadel Colour" paints, and companies that make paints to supplement display model lines, such as Scale75's "Scalecolor" paints. Water based acrylic paints are most common, however some companies also make gel-medium based acrylic paints, such as "Warcolour" paints. The major benefits of acrylic paints over enamel paints are the faster drying time, that acrylics can be thinned with water, that various mediums and additives (eg retarders, surfactants, etc) can be mixed in to assist in painting, that multiple thinned and semi-transparent layers of paint can be used to create blending and effects, and being non-toxic. For all of their advantages, acrylic paints are the most popular choice among figure painters, with the majority of painters, particularly display and competition painters, using exclusively acrylic or mostly acrylic with some other paint types used for achieving specific effects, although some figure painters still use enamels out of personal preference or nostalgia. As well as acrylic paints formulated for figure painting, it is possible to use regular "heavy body" acrylics to achieve highly detailed results, provided they are of a high artist grade quality.
