Ultra red is a color formulated by Crayola in 1972. In 1990, the name of the color was changed to wild watermelon . With a hue code of 350, this color is within the range of carmine colors. This color is supposed to be fluorescent, but there is no mechanism for displaying fluorescence on a computer screen.
Iron oxide red is a generic name of a ferric oxide pigment of reddish colors. Multiple shades based on both anhydrous Fe. 2O. 3 and its hydrates were known to painters since prehistory. The pigments were originally obtained from natural sources, since the 20th century they are mostly synthetic.
