Helio#BE00FF, a vivid purple

At a glanceHelio is #BE00FF, oklch(60.8% 0.303 312.7), a vivid purple, fully saturated at the sRGB gamut edge for its hue. Its hue sits mid-wheel, neither warm nor cool. Partner it with a cool bright aqua #78EBCF as an accent, a warm rich pink #E4609F for harmony, and a muted purple #7F7485 as a neutral. Try it as a screen-first brand or accent color, and it takes black text at AA contrast. It shifts further on press than a run can hold, though, so Rhapsody would keep it off print-led brand work.

The name

Why is it called Helio?

Helio's meaning, origin, and pronunciation, with sources.

Anchor: A62 · one of the 72 anchor hues of ART

Origin: Greek: the sun, via a flower that turns to face it

Meaning: A clipping of heliotrope, "turning toward the sun"

HEE-lee-oh · /ˈhiːlioʊ/

Proto-Indo-European *sóh₂wl̥, the root behind Latin sol and English sun → Greek hēlios, "sun" → hēliotropion, "turning toward the sun," the name of the plant whose flowers track the sun across the sky → heliotrope, the pale purple of its blooms, a color name from the 1880s → shortened, here, to helio.

So the wheel's softest purple is, at root, the sun itself, named for a flower's habit of devotion.

One oddity for collectors: heliotrope is also the old name for bloodstone, a green-and-red gem. That makes it a rare case of one word naming two completely unrelated colors. Even inside a single language, a color word can lead a double life.

etymonline s.v. heliotrope, helio-. Etymological dictionaries + scholarly sources. Audio: synthesized (en_US-lessac-medium).
