Sturdy Phoenicia

#64238b
Notes

Sturdy Phoenicia (#64238B) is a deep indigo 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 (278°, 60%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sturdy
adjective

Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.

Phoenicia
noun

The ancient Levantine coast (modern Lebanon and northern Israel) — the Greek-named Phoinikē (purple-people) civilization whose maritime traders carried Tyrian purple across the Mediterranean from 1500 BCE. Phoenicia color refers to a Phoenician purpura-dyed trade textile excavated from a Sidon tomb: a saturated, slightly cool deep violet with the matte finish of multi-bath shellfish-dye on hand-loomed Levantine wool.

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.
