Spartan Leo Hibiscus

#ad365c
Notes

Spartan Leo Hibiscus (#AD365C) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (341°, 52%, 45%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Spartan

Greek Spartiátēs, of Sparta — adjectival suffix referring to the Lacedaemonian warrior city.

As a color modifier, leo implies a lion-and-fire-sign-and-Sun-ruled-fixed-fire quality, the visual register of Hellenic-Leo-and-Nemean-lion hand-lion-and-fire-sign-and-Sun-ruled-fixed-fire Hellenic-Leo-and-Nemean-lion-and-Hercules-twelve-labors leo-and-lion-and-fire-sign surfaces under Hellenic-Leo-and-Nemean-lion-and-Hercules-twelve-labors high-summer-and-July-and-August fixed-fire-sign-light.

Hibiscus
noun

Hibiscus rosa-sinensis — the showy mallow of Pacific gardens, the Hawaiian state flower, the source of the deep red sorrel tea sold across West Africa as bissap.
