Engulfed Speedwell

#372463
Notes

Engulfed Speedwell (#372463) is a deep indigo 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 (258°, 47%, 26%) 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

Engulfed
adjective

Old French en-golfe, into-the-gulf — past-participle of engulf. As a color modifier, engulfed implies the deep-overwhelming-and-cool quality where the hue has been completely surrounded by darkness, like a small boat overtaken by Atlantic-ocean swells. Sits at the deep-and-overwhelmed end of the grid, parallel to submerged and suffocating.

Speedwell
noun

Veronica chamaedrys, the small-flowered creeping speedwell of European hedgerows and lawn margins — named speedwell in folk Latin for its old reputation as a wound-healing herb. The color refers to a fresh speedwell flower: a saturated, slightly violet-shifted bright blue with the matte finish of a small four-petaled bloom. Cooler than periwinkle, warmer than cornflower, with the wildflower weight of a plant most often noticed by accident in a lawn.

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.
