Like no other insulators ever made. Besides this 102, ... 126's, 133's, and 145's are all known in similar shades, the 145 being the most common of the lot. The colors of this group are affected hugely by what light they are viewed in. This insulator washes out to a chalky, Necco candy-like purple color in sunlight, but in refracted light like the shine off snow makes it look a deep grape juice shade.
