You want a blue with real depth — not washed-out, not neon. Derwent Chromaflow in Deep Sea delivers that rich, saturated tone with a smooth laydown from the first stroke. The premium core holds firm under sharpening and sustained pressure, so you're not re-sharpening every two lines. It blends cleanly with other Chromaflow blues and warms up well against earth tones. A dependable, all-round blue for sketching, illustration, or a classroom set that actually gets used
