As our vehicles get older, we begin to notice more and more differences from those manufactured decades ago; however, one aspect that hasn’t necessarily scrutinized as much color.

However, it only until 1915 when German-American chemist Walter Reppe discovered a way to make zinc chromate more durable. The pigment what chemists call substantive meaning it holds its shape even after being mixed with other pigments.

Cadmium Yellow

In 1863, a German chemist discovered that cadmium yellow (named after Cadmus, in Greek mythology) was one of a class of chemical compounds called chromates. These used as pigments since ancient times but were toxic to humans when used in large quantities. By carefully heating chromate compounds, chemists able to reduce their toxicity and increase their yield—allowing them to used in paints, coatings, and plastics. Cadmium yellow also unique among chromates. Because it an intense color that lasted well without fading or changing over time.

Since cinnabar is toxic, it not used in modern paints except when applied thinly on watch dials. In fact, cinnabar still sometimes used as a very thin layer of gold coating in Chinese calligraphy brushes.

Anhydrous Tin Oxide (Stannous Chloride)

Anhydrous tin oxide a relatively new addition to pigments, with use beginning in 1883 and becoming more popular as time progressed. It developed as an alternative to white lead and zinc oxide, which very common in paints before it came along. White lead found to dangerous, resulting in its removal from most paints by law. Anhydrous tin oxide made by mixing two elements: tin and oxygen (meaning an-hydrous means without water). As you might guess from its color, anhydrous tin oxide gives off a red hue when used in paint (among other things). This pigment commonly referred to as either ATO or SnO2.

Brown Iron Oxide (Iron III oxide – FeO)

Brown iron oxide one of four main pigments used by artists to create their masterpieces. Brown iron oxide known to a great pigment.
