The natural color of ebonite is black, the only other colors that can be obtained with relative ease are orange, thanks to the use of cinnabar, or dark red (with the use of hematite).<ref>for more technical details you can refer to this [https://web.archive.org/web/20120106092952/http://www.kamakurapens.com/Archive/TheRHRPen.html article].</ref> This has given rise to several processes, from the classic [[RHR|red hard rubber]], to the various combinations of red and black ebonite ([[Mottled]], [[Rippled]], etc..) up to the production, carried out essentially by the [[Waterman]]<ref>even if some [[Tibaldi]] [[Tibaldi Flattop|models]] in coloured ebonite are known.</ref> in its obstinacy not to abandon this material, of colours such as green, blue, yellow and pink. But in the end none of these colours could compete with the brilliance offered by the new materials, and in particular by the [[celluloid]], and ebonite has been progressively abandoned as a material used for the body of the pen, remaining however used until today in the production of the [[feed]]s, even if today this happens only for the most valuable pens, since this material cannot be moulded.
