puce (n.)youdaoicibaDictYouDict
"brownish-purple," 1787, from French puce "flea-color; flea," from Latin pucilem (nominative pulex) "flea," from PIE *plou- "flea" (cognates: Sanskrit plusih, Greek psylla, Old Church Slavonic blucha, Lithuanian blusa, Armenian lu "flea"). That it could be generally recognized as a color seems a testimony to our ancestors' intimacy with vermin.
