Stable Pillar Denim
Stable Pillar Denim (#294E83) is a deep azure with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (215°, 52%, 34%) 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
Latin stabilis, standing-firm — sharing root with stand. As a color modifier, stable implies a clear-and-firm-and-unchanging quality where the hue carries the visual register of resistant-to-modulation-and-fade pigmentation. Sits at the crisp-and-firm end of the grid, parallel to steady and settled in usage.
Latin pīla, pillar. As a color modifier, pillar implies a vertical-load-bearing-and-monumental quality, the visual register of Roman-and-Greek-and-Egyptian-Pillar hand-cut Doric-and-Ionic-and-Corinthian-Egyptian column-and-pillar monumental-architecture surfaces under classical-pillar monumental-architecture light. Sits at the modifier-and-architecture end of the grid, parallel to column and plinth in usage.
The diagonal-twill cotton fabric originally woven in Nîmes, France — serge de Nîmes, contracted to denim — and dyed with indigo since at least the eighteenth century. The color refers to a worn but un-faded pair of raw denim jeans: a saturated, slightly muted blue with the matte finish of cotton fiber that has absorbed dye through generations of weft and warp. Cooler than royal, warmer than navy.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
