Golden Artist OPEN COLORS Acrylics are a slow-drying paint with a slightly softer consistency than the Heavy Body paints from Golden.

The increased working time of these acrylic paints allows artists to use more traditional oil-painting techniques when working with them. Thick applications can dry extremely slowly, so it is recommended artists only use these OPEN Colours thinly (<1mm). The drying time can be accelerated by mixing OPEN with faster-drying acrylics like the Golden Fluid and Heavy Body ranges.

The slow-drying capability of OPEN Acrylics also makes them suitable for some printmaking techniques.

Due to the slower drying time of OPEN Acrylics, artists can se the paints for weeks when covering palettes or using sealed containers. This reduces the amount of paint wasted and preserving colour mixtures for future use.
