Nightfall Ridge
Five stops tuned to sit together without fighting — #006065 ink anchors the set, #7cd3d9 opens it up, and #008d94, #37a9b0, #5fb6bc cross the middle in a tetradic arrangement. Nightfall Ridge suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
