Thai nielloware — kruang thom from Nakhon Si Thammarat — fills deeply engraved bright silver with a dense black niello alloy, so fine floral scrollwork glints against an almost lightless ground. The black thom dam is prized for being solid, even, and spotless; the engraved silver line is the signature gesture.

This design system distills that craft into pixels: a near-black ground carrying a faint cool tint, bright tarnish-edged silver as the active mark, engraved formal capitals, and gilded thom thong gold reserved for the rarest accents.
