The Faber-Castell Pitt Pastel Blue 153 colored pencil offers an intense and deep blue shade, ideal for defining shadows and creating aquatic or nocturnal atmospheres. With very high-quality pigments, it offers a smooth application that blends easily with fingers or a blending stump. The blue 153 color retains its opacity and vibrancy after final setting. It is recommended to sharpen the wood and lead exclusively with a blade or X-Acto knife.
