Made by GOLDEN in the USA, these Artist Acrylics are known for their exceptionally smooth, thick buttery consistency. They contain the largest assortment of unique pure pigments in a 100% acrylic emulsion vehicle available to the professional artist. These colours offer excellent permanency and light fastness. There are no fillers, extenders, opacifiers, toners or dyes added. Each Heavy Body colour is formulated differently depending on the nature of the pigment. Colours that tolerate higher pigment "loads" dry to a more opaque, matte finish. Colours that are more reactive and do not accept high pigment loading dry to a glossy finish and tend to be more transparent. Heavy Body colours contain no additives, such as matting agents, therefore the gloss of each colour will be different. This range of 60ml tubes includes 96 regular colours, 7 neutral greys (a series of achromatic greys that follow the Munsell Value Scale and allow artists to adjust value and chroma without altering hue) and 24 iridescent and interference colours.
