The Faber-Castell Pitt Pastel Blue 157 colored pencil provides a rich, purplish-blue hue, perfect for creating dramatic contrasts and glazes in illustration work. The high density of the grease-free pigment allows for successive layers to be applied without saturating the paper texture. The Blue 157 color adheres easily and resists light fading. To preserve the pastel lead, sharpen it only with an X-Acto knife.
