Dianisidine Orange is a semi-opaque orange dye that can be laked to form a pigment. This pigment ranges from yellowish to reddish orange in different laked forms.
Dianisidine Orange has only fair lightfastness.
A Japanese study in which rats were given large daily doses of Dianisidine Orange revealed no acute toxicity or mutagenic effects.
Dianisidine Orange is used mostly in coloring plastics and in inks, in applications where safety is important but lightfastness and longevity are not paramount.

Yellow Ochre provides artists with earthtones from cream to brown. It has good hiding power, produces a quick drying paint, and can be safely mixed with other pigments. Its transparency varies widely from opaque shades to more transparent ones, which are valued for their use as glazes. If gypsum is present, Yellow Ochre is not suitable for frescoing. (See Brown Ochre, PY43.) PY42 is made from synthetic iron oxides. PY43 is made from natural iron oxide.
Yellow Ochre has excellent permanence because ochres are some of the most permanent pigments available.
Yellow Ochre is non-toxic unless it contains manganese.
Ochre comes from the Greek word ochros, meaning pale yellow. It was one of the first pigments to be used by human beings, and evidence of its use has been found at 300,000 year old sites in France and the former Czechoslovakia.
