What are the drying times for Winton Oil colours?
All colours will become touch dry in 2-12 days. The different drying rates are due to the different reaction of each pigment when mixed with oil. Winsor & Newton formulate colours to optimize drying rates, helping artists to avoid the problems of slow drying underlayers. However, the following list is a guide to the likely variations: Fast drying (around 2 days): Prussian Blue, Raw Sienna, Umbers. Medium Drying (around 5 days): Phthalo Blue and Viridian Hue (phthalocyanines), Burnt Sienna, Ultramarine Blues, Synthetic Iron Oxides, Ochres, Titanium White, Zinc White, Lamp Black, Ivory Black. Slow Drying (more than 5 days): Cadmium Hues (arylamides), Permanent Rose (Quinacridone), Alizarin Crimson Hue. As with all oil paintings, to avoid yellowing of the oil, paintings should not be allowed to dry in places with continuous darkness or high humidity.
