Terracotta Fen
Five stops tuned to sit together without fighting — #00657b ink anchors the set, #7fd8f4 opens it up, and #0091b0, #39adcd, #62bbd6 cross the middle in a monochromatic arrangement. Terracotta Fen suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
