W&N Galeria acrylic colors 60 ml

Acrylic paints are water-soluble when wet but dry to be waterproof and matte. The acrylic binder in acrylic paints is white when wet but dries transparent, which is why acrylics usually darken slightly as they dry.

We recommend using a painting medium specifically designed for acrylics, although water can also be used for thinning. With mediums, you can easily adjust the thickness, gloss level, and drying time of the paint, and the color remains stable without breaking down as it might when using water alone. Varnish can be used to adjust and even out the gloss level of a finished painting.
