OPEN Acrylics are colours for professional artists designed with a unique set of working properties that represent a true departure from all other acrylics on the market and dramatically expand the range of techniques that are available to artists. OPEN Acrylic Colours are formulated with an optimum balance of pigment load and 100% acrylic polymer dispersion to produce a paint with a uniquely relaxed set of working characteristics and a versatility that allows artists to explore a wider range of techniques such as portraiture and landscape painting that rely on softening, shading, glazing, and creating fine detail. OPEN Acrylics are a slow-drying paint with a slightly softer consistency than our Heavy Body paints. The increased working time of these colours expands their range to include more traditional techniques once only possible with oils. Because OPEN Acrylics dry slowly, painters who cover their palettes or use sealed containers have been able to use the same colours for weeks, reducing the amount of paint wasted and preserving colour mixtures for future use.
