紫色可以是從紅加藍而成，這是無容置疑。555Please respect copyright.ＰＥＮＡＮＡSmKCa8M5X4
但古時候的人又是從甚麼途徑獲取紫色顏料呢?555Please respect copyright.ＰＥＮＡＮＡhkiVHndseu

(圖2）紫色顏料其中的一道渠道，就是從骨螺而來。555Please respect copyright.ＰＥＮＡＮＡK9fIv51Qc2

顏色的來源當然並非來自骨螺外部，而是來自內部一道名為鰓下腺(Hypobranchial gland)的器官。555Please respect copyright.ＰＥＮＡＮＡXZackIcJZn

提取過程相當複雜，而且顏色最終的光澤將取決於骨螺的新鮮度，平均來說每隻骨螺最終只可提取得到約0.9克的顏料。555Please respect copyright.ＰＥＮＡＮＡur3kmeBfYb

（圖3）從以色列南部找出屬於約3000年前(鐵器時代)的紫色羊毛纖維中，找到骨螺鰓下腺器官內含的6-monobromoindigotin和6,6-dibromoindigotin的化學物質，進一步引證從骨螺提取紫色顏料的證據。555Please respect copyright.ＰＥＮＡＮＡItEUyNGRJB

據稱，從骨螺而來的紫色染料一律將被命名為True Purple或是Royal Purple，對比其他來自植物或礦物得來的紫色染料，較不容易會褪色。555Please respect copyright.ＰＥＮＡＮＡljT8VvdvWQ
