Mtundu wachikasu wa Chrome, womwe umadziwika kuti lead chromate (PbCrO₄), ndi utoto wowala komanso wowala womwe umatchuka kwambiri chifukwa cha mtundu wake wowala. Poyamba unapangidwa mu 1809 ndi katswiri wa zamankhwala wa ku France Louis Nicolas Vauquelin, ndipo unatchuka mofulumira ngati njira ina yotsika mtengo m'malo mwa utoto wachikasu wachikhalidwe monga orpiment. Dzina la utotowu limachokera ku chromium, chinthu chomwe chinapezeka panthawi yoyesera kwa Vauquelin pa crocoite ya mchere, yomwe ndi gwero lachilengedwe la lead chromate.
Kupanga kwa chrome yellow kumaphatikizapo njira ya mankhwala yothira madzi. Mchere wa lead umalumikizana ndi chromate kapena dichromate compounds mu madzi, ndikupanga tinthu tating'onoting'ono ta lead chromate. Mwa kusintha momwe zinthu zimachitikira, opanga amatha kupanga mitundu yosiyanasiyana, kuyambira yachikasu chopepuka cha primrose mpaka malalanje akuya komanso olemera. Tinthu tating'onoting'ono timapereka mitundu yopepuka, pomwe tinthu tating'onoting'ono timapanga mitundu yakuda. Kuti tiwonjezere kukhazikika ndi magwiridwe antchito, nthawi zambiri mankhwala ochizira pamwamba amagwiritsidwa ntchito, kuteteza utoto ku kuwonongeka kwa chilengedwe.
