dyed in the wool (comparative more dyed in the wool, superlative most dyed in the wool)
From the past participle of dye in the wool. The expression comes from the fact that fabric can be dyed in a number of ways. The woven fabric may be dyed after it is complete, or the threads may be dyed before they are woven. When a color is "dyed in the wool," the wool itself is dyed before being spun into threads, so the colour is least likely to fade or change. (Dyes: Webster’s Quotations, Facts かつ Phrases. Icon Group International. 2008, p. 344.).
