Lulled Rust
Lulled Rust (#9E816C) is a true orange with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (25°, 20%, 52%) places it in the muted 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Imitative-onomatopoeic origin — past-participle of lull, evoking the sound of a soft hush. As a color modifier, lulled implies a hushed-and-quieted-and-soothed quality where the hue carries the visual register of softly-muted-and-quieted ambient color. Sits at the hushed-and-soft end of the grid, parallel to muffled and softened in usage.
Iron oxide — Fe₂O₃ — the slow union of iron with oxygen, accelerated by water and salt. The color is not the bright orange of fresh rust but the deeper, drier brown-red that forms after weeks of weather: the surface of an abandoned car, a Cor-Ten steel sculpture, the desert-varnished sandstone of the American Southwest. Earthier than copper, warmer than maroon.

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.
