Kolinsky is the benchmark bristle for watercolour and oil painting: it holds a generous charge of pigment, releases it evenly from tip to belly, and snaps back to a fine point after each stroke. In watercolour, that translates to precise control over paint flow and clean line work across wet-on-wet and detail techniques. In oil, the softness and spring of Kolinsky sable makes it the preferred choice for glazing, smooth blending and fine detail where a stiffer bristle would leave too much texture. Raphaël offers Kolinsky in both red sable and synthetic fibres, covering fine point rounds for detail work, short rounds for broader washes, and long rounds for calligraphic and gestural line work.
