Kilt-Fabric - numbers for yarn-colors (color-system)?

[Tarheel]

I offer this small history lesson from my North Carolina family's past. My mom's family lived in a community named Cloverdale. The main industry was a dye works. They had their own chemist that created the colors for their dyes. The dyed spools were used to make fabric for Thomasville furniture (later including Basset). Accent pieces of furniture (from smaller independent companies) that matched the Thomasville or Basset main items were required to buy fabric dyed and supplied by the Cloverdale plant. There was no sharing of formulas in color palates.

Trademarks and patents of scientific property seemed to be the standard then and I expect still are the norm.
