Abstract: Dyeing a glass comprises carrying out a first dyeing process of the glass; determining a color difference of an attained glass coloration from a predetermined desired color in a specific color space; providing a dyeing model for the predetermined target color, which changes the glass coloring in the specific color space; determining values of the process parameters of the second dyeing process in such a way that the values associated with changes represents an at least partial compensation of the determined color difference; and performing the second dyeing process with the determined values. Dyeing a glass comprises (a) carrying out a first dyeing process of the glass, (b) determining a color difference of an attained glass coloration from a predetermined desired color in a particular color space, (c) providing a dyeing model in accordance for the predetermined target color, which changes the glass coloring in the specific color space, based on the predetermined desired color, depending on the process parameters, represents a second dyeing process, (d) determining values of the process parameters of the second dyeing process in such a manner that the values of process parameters to be determined by the dyeing model associated with change in glass coloring based on the attained glass coloration represents an at least partial compensation of the determined color difference, and (e) carrying out the second dyeing process with the determined values of process parameters. Independent claims are also included for: (1) creating a dyeing model comprising (a) manufacturing a common target color corresponding to manufacturing a variety of glasses, their color, (b) applying a second dyeing process in each case of multiple glasses, each with a reference value for multiple process parameters of the second dyeing process, where the glasses in pairs each, differs the reference value of at least one process parameter, and (c) detecting a second dyeing process resulted by the changes in the glass color for each of the multiple glasses in a specific color space; (2) a system for determining process parameters for dyeing the glass comprising (1) a color analysis module for determining the color difference of the glass coloring with a determined target color in the specific color space, attained in a first dyeing process, (2) a data storage for providing a model dyeing for the predetermined target color, which represents the basis of the predetermined desired color changes in the glass coloring in the specific color space depending on process parameters of a second dyeing process, (3) a parameter evaluation module for determining values of the process parameters of the second dyeing process in such a manner that the values of process parameters to be determined by the dyeing model associated with change in glass coloring based on the attained glass coloration represents an at least partial compensation of the determined color difference, and (4) a data output module for outputting the determined values of the process parameters; and (3) a computer program product comprising loading program code, and causing execution by the computer system to determine the process parameters for coloring the glass that includes (1a) determining a deviation of a color attained glass coloration of a predetermined target color in a specific color space in a first dyeing process, (1b) providing a dyeing model for the predetermined target color, which represents the basis of the predetermined desired color changes in the glass staining in the color space as a function of process parameters of a second dyeing process, (1c) determining values of the process parameters of the second dyeing process, and (1d) outputting the determined values of process parameters.
