A warm grey that shifts to brown or goes chalky after a year? That's not a pencil you want in a portfolio piece. The Derwent Lightfast pencil in Warm Grey keeps its tone locked in — rated for up to 100 years under museum conditions. Opaque laydown, strong point, and it sits cleanly between your warm browns and cool greys when you're building tonal range
