The story of Ruri
Ruri (瑠璃) is the vivid deep blue of lapis lazuli — the gemstone, not the dye. The colour is named after the stone, and the Buddhist Pure Land ('Eastern Lapis Realm') is where the pigment's cultural weight comes from. Where ai is everyday-blue, ruri is jewel-blue: saturated, slightly cool, and traditionally reserved for ceremonial textiles, religious paintings, and the most expensive lacquerware inlays.
Modern usage: luxury hospitality, premium beauty, anywhere the brief asks for a blue that reads as precious rather than functional. Ruri pulls darker and more saturated than hanada (the half-indigo blue), brighter than kon (deep navy), and richer than asagi.
