Work at your own pace and interact with your acrylics! With an extended curing time of five to seven days, Chroma Atelier Interactive acrylic paints stay wet on the palette and do not form a skin which allows blending and reworking of paint layers. The paint can continue to be manipulated even after it is touch-dry. Simply restore moisture with an atomizer spray and continue to interact with the paint. These intense colors are archival and lightfast with minimal color shift once dry.
