Open Alkanet

#efadb2
Notes

Open Alkanet (#EFADB2) is a soft red with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (355°, 67%, 81%) 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.

Alkanet
noun

Anchusa tinctoria, the Mediterranean borage whose roots yield a red dye used since classical times for cosmetics and wine coloring. The color refers to fresh alkanet-dyed wool: a saturated, slightly cool deep red with the matte finish of plant-and-mordant dye. Cooler than madder, deeper than crimson.
