The method exploits the rose natural processes by which water is drawn up the stem. By splitting the stem and dipping each part in water with added dye in different colours, the colors are drawn into the petals resulting in a multicolored rose. With these changes to the rose, it causes them to not live as long as an uncolored rose. The colors are artificial.<ref name="CH 48 1">{{cite web|url=http://www.actahort.org/chronica/pdf/ch4801.pdf |title=Gilding the Lilies: Rainbow Roses and Confetti Poinsettias |work=Chronica Horticulturae - Volume 48, Number 1, 2008 |page=16 |author= António A.
