Trim Sora

#1f4f88
Notes

Trim Sora (#1F4F88) is a deep azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (213°, 63%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Trim
adjective

Old English trymman, to make firm — sharing root with firm. As a color modifier, trim implies a clear-and-neatly-arranged quality where the hue carries the visual register of carefully-edited surface-detail. Sits at the crisp-and-neat end of the grid, parallel to neat and tidy in usage.

Sora
noun

The Japanese word for sky — and sora-iro (空色), the standard Japanese name for sky-blue. Used in Heian-period waka poetry and ukiyo-e woodblock prints for the saturated mid-blue of clear summer skies. The color refers to a Japanese summer sky at midday: a saturated, slightly cool deep blue with the optical brightness of mid-latitude scattered sunlight.

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.
