Sylvan Cement
Sylvan Cement (#93867F) 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 (21°, 8%, 54%) 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
Latin silvānus, of-the-woods — adjectival suffix -an, derived from silva (forest). As a color modifier, sylvan implies a neutral-and-forest-and-woodland quality, the neutral color of English-and-Welsh deciduous-and-mixed-forest woodland-walking-and-ramble pastoral-and-natural color tone. Sits at the neutral-and-traditional end of the grid, parallel to bucolic and pastoral in usage.
Portland cement — a powdered binder of calcium silicate, alumina, and iron, mixed with water and aggregate to make concrete. Patented by Joseph Aspdin of Leeds in 1824 and named for its resemblance to Isle of Portland limestone. The color refers to dry Portland cement powder: a soft, slightly muted pale gray with the powdery finish of micron-ground mineral. Cooler than stone, warmer than dust.

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.
