Conquering Faun Indigo

#646cdc
Notes

Conquering Faun Indigo (#646CDC) is a true blue 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 (236°, 63%, 63%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Conquering
adjective

Latin conquīrere, to seek thoroughly — present-participle of conquer. As a color modifier, conquering implies a saturated-and-overwhelming-and-victorious quality where the hue overcomes neighboring colors through pure pigmentation strength. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and dominant.

Faun
modifier

Latin Faunus, Roman-half-goat-rural-deity. As a color modifier, faun implies a half-goat-and-pastoral-and-Arcadian quality, the visual register of Roman-Faunus-and-Arcadian-pastoral-faun hand-half-goat-and-pastoral-and-Arcadian Roman-Faunus-and-Arcadian-pastoral-faun-and-Pan faun-and-half-goat-and-pastoral-and-Arcadian surfaces under Roman-Faunus-and-Arcadian-pastoral-faun-and-Pan Lupercalia-and-Arcadia-and-pipes-of-Pan pastoral-Arcadian-light. Sits at the modifier-and-myth end of the grid, parallel to satyr and dryad in usage.

Indigo
noun

Indigofera tinctoria, the South Asian legume whose leaves yield the deep blue dye that has clothed humanity for at least four thousand years — Egyptian linen, Mayan textile, the slave-grown plantations of Carolina. The color refers to a freshly indigo-dyed cotton thread: a saturated, slightly violet-shifted deep blue with the slight lustre of a fiber surface oxidized in air. Deeper than cobalt, cooler than royal.
