Straightforward Lazulite

#054e8d
Notes

Straightforward Lazulite (#054E8D) is a deep azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (208°, 93%, 29%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Lazulite
noun

A magnesium-iron-aluminum phosphate mineral — distinct from lapis lazuli despite the etymological cousin. Mined principally in Yukon Territory (Canada) and Madagascar. The color refers to a polished lazulite cabochon: a saturated, slightly cool deep blue with the matte finish of opaque phosphate mineral.
