Drafted Kihachijō

#3588c3
Notes

Drafted Kihachijō (#3588C3) is a true azure with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (205°, 57%, 49%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Drafted
adjective

Old English draht, draft — past-participle of draft. As a color modifier, drafted implies a clear-and-line-and-measured quality, the crisp color of Mid-Century-Modern hand-drafted architectural-and-engineering studio-drawing precision-tool-rendered lines. Sits at the crisp-and-incised end of the grid, parallel to drawn and plotted in usage.

Kihachijō
noun

The traditional indigo-dyed silk of Hachijō island in Tokyo's southern archipelago — produced from native kobaicha (yellow-brown) and aogarami (deep blue) dyes since at least the eighteenth century. Kihachijō-iro refers to the saturated medium blue of the silk: a saturated, slightly cool deep blue with the satin finish of plant-dyed island silk.
