Glowing Tsuchi
Glowing Tsuchi (#DC9C36) is a true amber with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (37°, 70%, 54%) places it in the balanced 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
The progressive participle of glow, to emit light — used as a color word since the medieval period for hues that read as if they were luminous from within. Glowing amber, glowing rose: the implication is moderate saturation combined with the optical impression of internal light. Sits in the bright-bucket alongside radiant.
The Japanese word for earth or soil — used for the warm pink-tan of clay-walled tsuchi-kabe of Japanese farmhouses and the unfinished plaster of Kyoto teahouses. The color refers to a freshly applied tsuchi-kabe wall: a soft, slightly muted warm pink-tan with the matte finish of mud-and-straw plaster. Drier than terracotta.

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.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
