Resolute Nymph Violet

#666ac5
Notes

Resolute Nymph Violet (#666AC5) 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 (237°, 45%, 59%) 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

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Nymph
modifier

Greek νύμφη, nature-spirit-and-young-bride. As a color modifier, nymph implies a nature-spirit-and-grove-and-spring quality, the visual register of Hellenic-nymph-and-grove-and-spring hand-nature-spirit-and-grove-and-spring Hellenic-nymph-and-grove-and-spring-and-Arcadian-pastoral nymph-and-nature-spirit-and-grove surfaces under Hellenic-nymph-and-grove-and-spring-and-Arcadian-pastoral Mediterranean-grove-and-stream dappled-grove-light. Sits at the modifier-and-myth end of the grid, parallel to dryad and nereid in usage.

Violet
noun

Viola odorata, the European sweet violet — small, fragrant, and the original meaning of the color name in English (the Violet of the rainbow). The color refers to a fresh sweet violet blossom in late winter: a saturated, slightly red-shifted deep blue-purple with the matte finish of small five-petaled flower. Cooler than amethyst, warmer than indigo, with the perfumed weight of a flower used in Roman garlands and Victorian eau de toilette.

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.
