Rich Flurry Royal

#1c45a7
Notes

Rich Flurry Royal (#1C45A7) is a true 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 (222°, 71%, 38%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Flurry
modifier

Imitative origin, quick-burst-of-snow. As a color modifier, flurry implies a quick-burst-of-snow-and-light-and-fluttering quality, the visual register of Adirondack-and-Vermont-flurry hand-quick-burst-of-snow-and-light-and-fluttering Adirondack-and-Vermont-flurry-and-New-England-snow flurry-and-quick-burst-of-snow surfaces under Adirondack-and-Vermont-flurry-and-New-England-snow Adirondack-and-Green-Mountains-and-White-Mountains New-England-snow-light. Sits at the modifier-and-weather end of the grid, parallel to slush and thaw in usage.

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.
