Obsidian Fjord
Five stops tuned to sit together without fighting — #00546b ink anchors the set, #76c5e3 opens it up, and #007fa0, #349bbd, #59a9c6 cross the middle in a tetradic arrangement. Obsidian Fjord suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
