Sterile Violetta

#a38fda
Notes

Sterile Violetta (#A38FDA) is a soft 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 (256°, 50%, 71%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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

Sterile
adjective

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic in usage.

Violetta
noun

Italian for little violet (Viola odorata) — the diminutive form of viola, also the name of Verdi's tragic heroine in La Traviata (1853). Violetta color refers to a freshly cut Viola odorata nosegay: a saturated, slightly cool deep blue-violet with the velvet finish of fresh viola petals. Richer than viola (the broader genus name) and less wisteria-warm than glicine.

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.
