Dim Brunnera

#0a3e9d
Notes

Dim Brunnera (#0A3E9D) 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 (219°, 88%, 33%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Dim
adjective

Old English dim, dark, obscured. As a color modifier, dim implies reduced luminance without specific saturation effect — a dim red is a less luminous version of red rather than a less saturated one. Sits at the value-only end of the deep grid, closer to dark than to plush.

Brunnera
noun

The genus BrunneraSiberian bugloss, the shade-garden perennial whose forget-me-not-style flowers appear in early spring. B. macrophylla 'Jack Frost' has silver-marbled foliage prized in shade gardens. The color refers to a fresh brunnera flower spike: a saturated, slightly cool deep blue with the matte finish of small five-petaled flower.
