GOLDEN OPEN Acrylics are a slow-drying formulation with a slightly softer consistency than GOLDEN Heavy Body paints. The increased working time of these colors 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 colors for weeks, reducing the amount of paint wasted and preserving color mixtures for future use.
One of the first synthesized pigments, this deep, nearly black color is alkaline sensitive so not found in acrylic paints. Our modern mixture provides a similar color with great permanence.
