SUBSTANCE: invention relates to coating compositions, particularly coating compositions with a decorative effect, which enable to obtain multi-colour and/or different-tone surfaces when applied once. Initially, the single-colour coating composition contains a first dye, a thickener, a surfactant or a mixture of surfactants with hydrophilic-lipophilic balance (HLB) less than 9 or greater than 11 and binder. All components are dispersed or dissolved in an organic solvent and water. After deposition of the said composition in form of a film onto a substrate surface which is a wall or ceiling panel, the first dye becomes incompatible with the said composition, as a result of which a portion of the first dye migrates towards the outer face of the panel while the coating composition is still in liquid state. Additional decorative effects are achieved by sliding the surface using a putty spittle or some other instrument while the coating composition is still in liquid or quasi-liquid state. The set for applying the decorative coating onto the surface contains the said composition and a label.

EFFECT: obtaining a ready coating having two differently-coloured zones, colour contrast (ΔE) between which is greater than 0,25.
