Local Yamiyo
Local Yamiyo (#07081F) is a deep blue 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 (238°, 63%, 7%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin locālis, of-a-place — adjectival suffix -al. As a color modifier, local implies a neutral-and-place-rooted-and-traditional quality, the neutral color of farm-to-table-and-100-mile-diet local-and-place-rooted artisanal-craft food-and-textile-and-pottery surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to regional and vernacular in usage.
Japanese 闇夜, dark night — the moonless overnight period of the lunar cycle, used in classical waka poetry for the absolute darkness of new-moon nights. Yamiyo color refers to a clear-sky moonless winter night sky over the Sea of Japan: a saturated, slightly cool deep black with the optical complexity of starlit-but-moonless atmospheric Rayleigh scattering. Deeper than yoru (general night) and warmer than astronomical zenith.

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.
