You need a blue that sits between the deep smalt and the bright cobalt. Something that reads as 'sky' rather than 'ocean.' The Derwent Artists Pencil in Spectrum Blue 3200 is that middle note. Round barrel, colour-grade lead, made for layering and blending so you can nudge the tone a fraction warmer or cooler without switching to a marker. One pencil, one specific blue, done
