You've got the sky blue, you've got the prussian blue, but that middle shade where the colour starts to feel alive? That's Indigo Blue 3600. The Derwent Artists Pencil in this shade is a round-barrelled, colour-grade pencil that sits right in the expressive range. Layer it, blend it, push it into a twilight scene or a denim jacket sketch and it responds. No waxy resistance, no frustration mid-stroke. Just a rich, reliable indigo that does what you tell it to. Grab one and see the difference in your next piece
