Honest Sanded Lazuli

#2a5c9b
Notes

Honest Sanded Lazuli (#2A5C9B) 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 (213°, 57%, 39%) 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

Honest
adjective

Latin honestus, honorable — used as a color modifier since the seventeenth century for hues that read as straightforward and unembellished, the working browns and grays of vernacular architecture rather than the polished shades of court fashion. Honest brown, honest gray: moderate saturation combined with optical directness. Sits at the crisp-bucket alongside plain and frank.

Sanded
modifier

Old English sandian, to-sand. As a color modifier, sanded implies a hand-sanded-and-smoothed-wood quality, the visual register of Shaker-and-Mid-Century-Modern-sanded hand-sanded-and-smoothed-and-finished wood-and-stone-and-metal Shaker-and-Mid-Century-Modern hand-sanded-and-smoothed surfaces under Shaker-and-Mid-Century-Modern hand-sanded-and-smoothed workshop-light. Sits at the modifier-and-texture end of the grid, parallel to honed and buffed in usage.

Lazuli
noun

Passerina amoena, the lazuli bunting — a North American songbird whose males display saturated deep-blue plumage with white wing bars and chestnut breasts. Named for the gemstone (lapis lazuli) the bird's plumage resembles. The color refers to a male lazuli bunting in breeding plumage: a saturated, slightly cool deep blue.
