Straightforward Heki

#a3b8ee
Notes

Straightforward Heki (#A3B8EE) is a soft azure with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (223°, 69%, 79%) 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

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

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.

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.
