Dim Onando

#1a3e97
Notes

Dim Onando (#1A3E97) is a true 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 (223°, 71%, 35%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Dim
adjective

Old English dim, dark, obscured. As a color modifier, dim implies reduced luminance without specific saturation effect — a dim red is a less luminous version of red rather than a less saturated one. Sits at the value-only end of the deep grid, closer to dark than to plush.

Onando
noun

Japanese onando-iro (御納戸色) — honored storehouse color, the saturated grayed-blue of pre-modern Japanese clothing storehouse interiors. Traditional Edo-period onando was used in samurai household interiors and the linings of formal court dress. The color refers to a onando-painted Edo storehouse wall: a saturated, slightly cool deep blue-gray with the matte finish of weathered distemper paint.

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.
