Lullaby Grove
Five stops tuned to sit together without fighting — #007273 ink anchors the set, #8ce6e7 opens it up, and #209fa1, #48bcbd, #6ec9ca cross the middle in a tetradic arrangement. Lullaby Grove suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
