METHOD OF DETERMINING MATCHING COLOUR VERSION Russian patent published in 2013 - IPC G01J3/46 

Abstract RU 2498240 C2

FIELD: physics.

SUBSTANCE: method comprises the following steps: determining the standard colour matching the colour of the object to be repaired and determining the best matching version of the standard colour from a given number of version colours, wherein a sample coated with the paint of the standard colour is visually compared under at least two different angles of illumination and/or observation with the colour to be matched, and the visual deviation from the standard colour and the colour of the object to be matched is evaluated based on predetermined deviations for visual properties, wherein the predetermined visual properties include at least one colour property and at least one texture property. Based on the predetermined deviations for the visual properties of the standard colour and the colour of the object to be matched, the best matching version of the standard colour is determined.

EFFECT: reliable colour matching of repair paints without using a data base of samples of all possible colours, and also without using expensive and sensitive equipment such as spectrophotometers and computers.
