Which of the following give a violet or blue colouration with neutral $\mathrm{FeCl}{}_3$? (more than one may be correct)

Compounds with a phenolic $-\mathrm{OH}$ form coloured complexes with $\mathrm{Fe}{}^{3+}$. Phenol, 4-methylphenol and salicylic acid all have one. Benzyl alcohol has an alcoholic $-\mathrm{OH}$ and gives no colour.
