Marigold Beacon
Five stops tuned to sit together without fighting — #00648b ink anchors the set, #8fd6ff opens it up, and #008fc6, #38abe4, #61baeb cross the middle in a monochromatic arrangement. Marigold Beacon suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
