Suffocating Phlox

#2f2188
Notes

Suffocating Phlox (#2F2188) is a deep blue 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 (248°, 61%, 33%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Suffocating
adjective

Latin suffocāre, to choke — present-participle of suffocate. As a color modifier, suffocating implies a deep-and-overwhelming-and-pressing quality where the hue overwhelms the eye's capacity to discern surface detail. Sits at the deep-and-overwhelming end of the grid, parallel to smothering with breath-restricting register.

Phlox
noun

The genus Phloxflame in Greek, for the brightness of its flower colors. P. subulata is the creeping moss phlox of rock gardens; P. paniculata is the tall summer-border phlox in cottage gardens. The color refers to a fresh blue-violet phlox cluster: a saturated, slightly violet-shifted blue-purple with the matte finish of densely packed five-petaled flowers. Cooler than wisteria, warmer than veronica.

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.
