Open Geranium

#ef9a90
Notes

Open Geranium (#EF9A90) is a soft red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (6°, 75%, 75%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

Geranium
noun

The genus Pelargonium (commonly called geraniums in English horticulture) — particularly P. zonale and P. peltatum, the bright red-flowered geraniums of European balconies and hanging baskets. The color refers to a fresh red geranium bloom in summer: a saturated, slightly orange red with the matte finish of small clustered five-petaled flowers. Brighter than scarlet, warmer than tomato.

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.
