BLUE תְּכֵ֫לֶת, H9418: a color extracted from the mollusk Helix Ianthina (LXX, ὑάκινθος, G5611). Pliny (Nat. Hist. XXI, 45) calls it amethyst, but this represents some confusion on his part (Forbes, Studies in Ancient Technology, IV, 119). It is a color derived by varying the process of extraction (ibid., p. 119). No specifications of intensity by which to define colors are or were available, most of the dyes being secrets of individual families (ibid., p. 100).

Modern tests have been developed to identify positively this dye. The use of it in Rome dates from earliest times.
