Adamant Phoenicia

#a663d8
Notes

Adamant Phoenicia (#A663D8) is a true indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (274°, 60%, 62%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Adamant
adjective

Greek adámas, unconquerable — derived from a- (not) plus damnan (to subdue). As a color modifier, adamant implies a saturated-and-rock-hard quality where the hue maintains diamond-hard pigmentation. Sits at the bold-and-resilient end of the grid, parallel to indomitable and ironclad in usage.

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.
