A brush and a knife
Seascape at Les Saintes-Maries-de-la-Mer
In addition to brushes, Van Gogh also used a palette knife in making this painting. With the knife, he spread the paint into a glossy, transparent layer in some places. This created the effect of sunlight on the waves and brought the colours to life.
In some places, the palette knife smoothed out the distinctive texture of the brushstrokes. Van Gogh did not often use a palette knife.
