This application allows defining in a backoffice frontend the primary and secondary colors to override those existing in the theme defined for each module. To do this, you must create the customizer record in the provided frontend application, define the start and end dates of use, and, in the frontend module that you want to verride, consume the client action "SetCustomizer" existing in the module " ColorCustomizer_Lib" and put it in the OnApplicationReady action, putting the name of the desired customizer in the input (see printscreens).
