Spartan Pisces Royal

#3b66d6
Notes

Spartan Pisces Royal (#3B66D6) 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°, 65%, 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

Spartan
adjective

Greek Spartiátēs, of Sparta — adjectival suffix referring to the Lacedaemonian warrior city. As a color modifier, spartan implies a saturated-and-disciplined-and-formal quality, the deep-rich color of Spartan-hoplite military-class crimson-and-bronze armor-and-cloak. Sits at the bold-and-formal end of the grid, parallel to austere and stern in tone.

Pisces
modifier

Latin pisces, fishes-of-the-zodiac. As a color modifier, pisces implies a two-fishes-and-water-sign-and-Jupiter-Neptune-ruled-mutable-water quality, the visual register of Hellenic-Pisces-and-Aphrodite-Eros-fishes hand-two-fishes-and-water-sign-and-Jupiter-Neptune-ruled-mutable-water Hellenic-Pisces-and-Aphrodite-Eros-fishes-and-Ichthys pisces-and-two-fishes-and-water-sign surfaces under Hellenic-Pisces-and-Aphrodite-Eros-fishes-and-Ichthys late-winter-and-February-and-March-into-April mutable-water-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to aquarius and aries 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
