Kool Aid-dye some wool red, blue, and purple to create the three colors of the Mishkan's famous tapestries and priestly clothing. Red (tola'at shani): See a New-World cochineal snail, which gives a dye similar to the Old World kermes biblicus of the Torah. [When the New World was discovered, cochineal replaced the more-expensive kermes dye in Europe. The British Red Coats were of two types: The Infantry's dull-red jackets were from the cheaper plant dye "madder"; the Officers' flashier-red jackets were due to the brighter, and more expensive, cochineal snail.]. Blue (techeilet): See a murex trunculus shell, likely the chilazon sea creature from which techeilet was extracted, and see wool dyed techeilet, which Rambam notes is identical in color to the pant-derived indigo. Purple-dark red (argaman): Learn a twining technique to create a color of two or three yarns woven together, showing why the Raavad, Kley HaMikdash, thinks the color argaman comes from the root "arg"--woven.
