[edit] Religion Blue in Judaism: In the Torah[6], the Israelites were commanded to put fringes, tzitzit, on the corners of their garments, and to weave within these fringes a "twisted thread of blue (tekhelet)".[7] In ancient days, this blue thread was made from a dye extracted from a Mediterranean snail called the hilazon. Maimonides claimed that this blue was the colour of “the clear noonday sky”; Rashi, the colour of the evening sky.[8] According to several rabbinic sages, blue is the colour of God’s Glory.[9] Staring at this colour aids in mediation, bringing us a glimpse of the “pavement of sapphire, like the very sky for purity”, which is a likeness of the Throne of God.[10] (The Hebrew word for glory.) Many items in the Mishkan, the portable sanctuary in the wilderness, such as the menorah, many of the vessels, and the Ark of the Covenant, were covered with blue cloth when transported from place to place.[11] Because blue is the color of the sky and sea, it has often symbolized divinity, as well as height and depth. ...
