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. Many of the rich reds and yellows are found in these paints as in the Golden Heavy Body Acrylics like the Cadmiums and Hansa Yellow and Pyrrole Red. Looking for transparent color try the Open Quinacridones.
GOLDEN sadly has discontinued making Quinacridone Crimson and Quinacridone Burnt Orange.
