Method for matching of a repair paint to texture properties (and optionally colour) parameters of a paint film on a substrate to be repaired, the repair paint being formulated on basis of concentrations of paint modules characterized in that each paint module is associated to specified texture (and optionally colour) data, and in that a calculational texture (and optionally colour) model using the texture (and optionally colour) data of the paint modules is used to calculate a repair paint with matching texture (and optionally colour) properties.
