A reddish dye made from the coccus insect, or kermes; hence, a red color of any tint or hue, as crimson, scarlet, etc.; sometimes used by the poets as equivalent to
Tyrian purple.
“All in a robe of darkest
grain.”
— Milton.
“Doing as the dyers do, who, having first dipped their silks in colors of less value, then give' them the last tincture of crimson in grain.”
— Quoted by Coleridge, preface to Aids to Reflection.
