Threadbare Smithsonite
Threadbare Smithsonite (#426252) is a deep teal 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 (150°, 20%, 32%) places it in the muted 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English thrǣd-bær, thread-bare — sharing root with thread. As a color modifier, threadbare implies a hushed-and-worn-and-faded quality, the hushed color of multi-decade farmhouse-and-cottage heavily-used-and-faded textile-and-rug surface where the warp shows through. Sits at the hushed-and-worn end of the grid, parallel to frayed and tattered in usage.
A zinc carbonate mineral — named for English chemist James Smithson (founder of the Smithsonian Institution). The blue-green variety is mined principally in New Mexico's Magdalena Mountains. The color refers to a polished blue-green smithsonite cabochon: a soft, slightly cool deep blue-green with the satin finish of botryoidal zinc-carbonate mineral.

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.
