Zusammenfassung:	Composition whereby ceramic manufactured articles are colored in shades from pink to violet, such composition includes of a monovalent gold thiolate water solution or mixture of water with a water soluble organic solvent according to the following formulas Au-S-R-X and Au-S-R-H, where R stands for a linear or branched bivalent radical of aliphatic or aromatic or cycloaliphatic or heterocyclic type optionally with substituents, such as for example aminic, amidic, hydroxylic, carboxylic, hydrocarbylic or carbonylic groups or CONH-, in the chain; X stands for a monovalent group selected out of -COOH, SO2OH, -OH, -CONH2, -NH2; O-P(O)(OH)2, in which H atoms may be replaced by alkyl groups and wherein acid group may be salified with amines or alkaline or alkaline earth metals and basic groups may optionally be salified with organic acids
