Porcelain Lagoon
Five stops tuned to sit together without fighting — #005287 ink anchors the set, #87c3f8 opens it up, and #337bb6, #5097d3, #6ba6da cross the middle in a monochromatic arrangement. Porcelain Lagoon suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
