In all probability this is the oldest pigment color ever used by humans. All of the oldest archeological evidence in which pigment remains were found, they were of Red Oxide. There is even evidence of Neanderthals using it to sprinkle on dead bodies, possibly to bring a semblance of life back to the skin. The oldest confirmed remnants of human usage are 60,000 years old in the caves at Pinnacle Point in South Africa, but there are more controversial artifacts over 100,000 years old. The oldest use of Red Oxide is probably as wet clays at the sides of rivers which were used to draw designs on the human body but unfortunately that is not the sort of thing to leave lasting remains via fossilization and will probably always be conjecture. Some cave remains in South Africa are of shells used as containers for red pigment but what exactly the pigment was used for is lost. It could potentially be anything from cosmetics, to decorations on tools and weapons, to ritualistic colouring for ceremonies. We will probably never know.

Yaelekea kwamba hii ndiyo rangi ya rangi ya kale zaidi ambayo wanadamu wamewahi kutumia. Utafiti wa kiakiolojia unaonyesha kwamba sehemu za nyuma za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi za rangi. Hata kuna uthibitisho kwamba watu wa Neanderthal walitumia mti huo kunyunyizia maiti, labda ili kurudisha uhai kwenye ngozi. Vitu vya kale zaidi vya utumiaji wa binadamu vimepatikana katika mapango ya Pinnacle Point, Afrika Kusini, lakini kuna vitu vya kale zaidi vya uthibitisho vinavyoweza kudumu zaidi ya miaka 10,000. Matumizi ya zamani ya Red Oxide ni kama udongo wa mvua kwenye kingo za mito ambayo ilitumiwa kuchora miundo kwenye mwili wa binadamu, lakini kwa bahati mbaya hiyo sio aina ya kitu cha kuacha mabaki ya kudumu kupitia fossilization na labda daima itakuwa dhana. Baadhi ya mabaki ya mapango katika Afrika Kusini ni ya makombora kutumika kama vyombo kwa ajili ya rangi nyekundu lakini nini hasa rangi ilitumiwa kwa ni kupotea. Inaweza kuwa kitu chochote kuanzia vipodozi, mapambo ya vifaa na silaha, hadi rangi za desturi kwa ajili ya sherehe. Yaelekea hatuwezi kamwe kujua.
