    Meanwhile, here's two color-octaves of anodized titanium.https://twitter.com/Rainmaker1973/status/1130120948085153792 …

    Anodizing titanium generates an array of different titanium color without dyes, for which it is sometimes used in art and jewelry. The color formed is dependent on the thickness of the oxide, which is determined by the anodising voltage https://buff.ly/2Py1DUF  pic.twitter.com/3YD4dohAA9

        Wifey @WhippetgirlLori uses titanium sometimes in her jewelry making. Heating it brings out some cool colors.
