silk of purplish color
緅 refers specifically to a type of silk fabric that is purplish in color. It is a narrow, material-focused term without broader abstract extensions.
緅 combines 糸 (silk) with 取, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a phono-semantic compound for a specific type of silk.
The left side 糸 means silk, and the right side 取 can suggest taking or selecting. Imagine selecting a special purplish silk thread from a bundle.
For シュウ, picture a bolt of purplish silk being shown at a fabric shop: 'show' -> シュウ, and the silk is displayed for selection.
