You need a dark green that actually reads as dark, not a muddy black-green that fades after two passes. Obsidian Green from Derwent Chromaflow gives you that depth with rich pigment and a smooth, confident laydown. The premium core takes the pressure of repeated sharpening and firm strokes without giving way. Layer it over lighter greens for shadow work or use it on its own for bold, graphic lines. Consistent from first stroke to last. No surprises
