Faint Heki

#c6cfef
Notes

Faint Heki (#C6CFEF) is a soft blue with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (227°, 56%, 86%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Faint
adjective

Old French faindre, to feign, weaken — used as a color modifier since the fifteenth century for hues that read as barely present. Faint pink, faint blue: very low saturation combined with high lightness. Sits at the pale-bucket extreme alongside whispered and ghostly.

Heki
noun

Japanese heki (碧) — a classical Sino-Japanese character spanning jade-green and deep-blue in pre-modern color vocabulary. Heki-iro names the saturated blue of polished imperial-grade nephrite. The color refers to a polished Japanese nephrite yu disc: a saturated, slightly cool deep blue-green with the satin finish of fine jade.
