The six base colours patterns are written in — the quantiser anchors of internal/colour (quantise.go), as a navigable palette.
These six colours are not a designer's choice but a statistical one: they are chosen to maximise explanatory power over the recorded corpus. Six anchors separate the patterns the dyers actually distinguished — fewer would collapse setts that differ on the loom, more would split shades no weaver treated as different roles.
