β-tin, also called white tin, is the allotrope (structural form) of elemental tin that is stable at and above room temperature. It is metallic and malleable, and has body-centered tetragonal crystal structure. α-tin, or gray tin, is the nonmetallic form.
Bismuth vanadate orange (PO86): non-toxic pigment similar to vermilion. Cadmium pigments. Cadmium orange (PO20): an intermediate between cadmium red and cadmium yellow: cadmium sulfoselenide. Chromium pigments. Chrome orange: a now obscure pigment composed of a mixture of lead chromate and lead(II) oxide (PbCrO 4 •PbO).
Historically the stibnite form was used as a grey pigment in paintings produced in the 16th century. [6] In 1817, the dye and fabric chemist, John Mercer discovered the non-stoichiometric compound Antimony Orange (approximate formula Sb 2 S 3 ·Sb 2 O 3), the first good orange pigment available for cotton fabric printing. [7]
Tin(IV) iodide, also known as stannic iodide, is the chemical compound with the formula SnI 4. This tetrahedral molecule crystallizes as a bright orange solid that dissolves readily in nonpolar solvents such as benzene .
Freshly prepared aqua regia is colorless, but it turns yellow, orange or red within seconds from the formation of nitrosyl chloride and nitrogen dioxide. It was so named by alchemists because it can dissolve noble metals like gold and platinum , though not all metals.

The color is caused by the size and dispersion of gold particles. Ruby gold glass is usually made of lead glass with added tin. Silver compounds such as silver nitrate and silver halides can produce a range of colors from orange-red to yellow. The way the glass is heated and cooled can significantly affect the colors produced by these compounds.
A study showed that 99.5% of the controlled food cans contain tin in an amount below that level. [4] However, un-lacquered tin cans with food of a low pH, such as fruits and pickled vegetables, can contain elevated concentrations of tin. [2] The toxic effects of tin compounds are based on its interference with iron and copper metabolism.
