You want a blue that actually reads as deep – not washed out, not grey. The Derwent Inktense Deep Blue block delivers that in one confident swipe. Use it dry for bold, textured strokes, or add water and let it settle into a translucent, ink-like wash. Big areas, small areas, same block. No running to the shop for a second tool
