Dim Wire Ultramarine

#1c2867
Notes

Dim Wire Ultramarine (#1C2867) is a deep blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (230°, 57%, 26%) 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 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.

Wire
modifier

Old English wīr, wire. As a color modifier, wire implies a thin-drawn-metal quality, the visual register of hand-drawn-and-coiled-wire hand-drawn-and-coiled iron-and-copper-and-gold thin-drawn-metal-wire-and-mesh surfaces under hand-drawn-and-coiled-wire workshop-light. Sits at the modifier-and-texture end of the grid, parallel to mesh and foil in usage.

Ultramarine
noun

The pigment ground from lapis lazuli — the Afghan mineral imported through Venice in the late Middle Ages, more expensive by weight than gold during the Renaissance. The color refers to a freshly mixed ultramarine pigment in linseed oil: a saturated, slightly violet-shifted deep blue with the matte finish of micron-ground rock. Deeper than cobalt, cooler than royal, with the art-historical weight of the blue Vermeer reserved for Mary's robe.

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.
