Velvet Iowa
Velvet Iowa (#1C2404) is a deep lime 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 (75°, 80%, 8%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
A short-pile woven fabric — silk, cotton, or rayon — whose densely packed vertical fibers absorb almost all incident light, producing a deeper black than the dye alone could give. The color refers to a black silk velvet: a deep, slightly muted black with the velvet's signature optical depth and the directional shading that distinguishes it from any flat fabric. Cooler than sable, deeper than ink.
The American corn-belt state — and the saturated yellow of Iowa cornfields at peak harvest, Iowa State athletic uniforms, and the Iowa Hawkeyes gold-and-black branding. Iowa refers to Iowa dent corn at harvest: a saturated, slightly red yellow with the matte finish of cured grain. Warmer than maize.

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.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
