You need a blue that actually shows up on the page in one confident stroke, not three hesitant passes. The Derwent Procolour Phthalo Blue 33 is highly pigmented and lays down with the covering power of wax and the glide of oil. It holds a strong point for fine detail work and gives you a clean, smudge-free line every time. Round barrel, vivid phthalo blue. If your current pencil keeps breaking or leaving a ghostly wash where you wanted a solid tone, this is the fix
