The Faber-Castell Pitt Pastel lilac 138 colored pencil offers a soft, elegant purple hue, perfect for botanical illustrations, shadows, and landscapes. Its wax-free formula ensures smooth, even application, allowing pigments to be mixed directly onto the paper surface. The lilac 138 color stands out for its high colorfastness in sunlight. To sharpen the soft pastel lead, a very sharp knife or artist's scalpel should be used.
