You've got the composition sketched, the light's mapped, and then you hit the grey. Most pencils give you a flat, chalky tone that sits on top of the paper instead of sinking into it. Derwent Coloursoft Petrel Grey C680 lays down a soft, velvety strip that builds depth fast — one pass for a shadow, three for a storm cloud. The round barrel sits naturally in your hand, so you can work long without the cramp creeping in. Whether you're rendering architecture, building a tonal study, or just need a grey that actually reads as grey on the page, this is the one
