Simple phenol (Carbolic acid) is almost colourless in aqueous solution but Naphthols forms pinkish or purple solutions.
Ag+ is colorless. (:
orange-red
yes, it turns in purple or a very light pink-ish purple color
yellow
Usually chromium with an oxidation state of +6 MnO4- will also impart a purple color in a solution

The solution of CuSO4 is blue.The solution of FeSO4 is green.
In an aqueous solution the solvent is water.
Amethyst is quartz that contains an impurity that imparts the purple color. The impurity in amethyst is iron.
The nitrate ion imparts no color to a solution.
The aqueous color disolved to .001 M of iron nitrate is purple or violet. (Not brownish orange). The individual crystals in a dry state are also a pale violet color.
"Addition of aqueous iron III chloride to a phenol gives a colored solution. Depending on the structure of the phenol, the color can vary from green to purple.
orange-red
It creates a clear aqueous solution with a blue tint.
In a neutral solution litmus has a purple color.
