Centered Eustoma

#342fb5
Notes

Centered Eustoma (#342FB5) 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 (242°, 59%, 45%) 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

Centered
adjective

Latin centrum, center — past-participle of center. As a color modifier, centered implies a saturated-and-grounded-and-balanced quality where the hue occupies the visual center of its palette without drift. Sits at the bold-and-balanced end of the grid, parallel to poised and grounded.

Eustoma
noun

Mexican-Texan prairie gentian (Eustoma grandiflorum) — marketed worldwide as lisianthus, a long-stemmed cut-flower industry staple with deep-violet rose-form blooms. Eustoma color refers to a freshly cut Eustoma grandiflorum fully opened bloom: a saturated, slightly cool deep blue-violet with the velvet finish of overlapping ruffled tepals. The Greek genus name eu-stoma means fine-mouthed, after the wide-throated corolla.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
