Firm Limed Royal

#3465e1
Notes

Firm Limed Royal (#3465E1) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (223°, 74%, 54%) 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

Firm
adjective

Latin firmus, strong / stable — sharing root with English farm (originally a fixed-yearly-rental). As a color modifier, firm implies a saturated-and-resolute quality where the hue holds its visual position without wavering. Sits at the bold-and-firm end of the grid, parallel to steadfast and unwavering in usage.

Limed
modifier

Old English līm, lime. As a color modifier, limed implies a lime-washed-and-whitened quality, the visual register of Andalusian-and-Mediterranean-limewashed hand-limed-and-whitewashed stone-and-stucco-and-timber Andalusian-and-Mediterranean-limewashed surfaces under Andalusian-and-Mediterranean lime-washed-and-whitened light. Sits at the modifier-and-texture end of the grid, parallel to mossed and pitted 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.
