Bice
BICE (from Fr. bis, a word of doubtful origin, meaning dark-coloured), a term erroneously applied in English to particular shades of green or blue pigments from the French terms vert bis and azur bis, dark green or blue. These colours are generally prepared from basic copper carbonates, but sometimes from ultramarine and other pigments.
