We have implemented custom TextMate tokens, with the help of which it is now possible to customize the colors of the logs in output channels:

Scope	Descriprion
rnt.output.string	Single and double quoted strings
rnt.output.url	Links, email and ip addreses, filepaths
rnt.output.timestamp	Date and time
rnt.output.numeric	Constant decimal numbers
rnt.output.process	Logs of processes such as npm, bundle, and other build tasks
rnt.output.error	Errors, exceprions, fails and stack for them
rnt.output.warn	Warning logs
rnt.output.info	Info logs
rnt.output.debug	Debug logs
rnt.output.verbose	Verbose logs
rnt.output.constant	Such values as true, false, null, undefined, NaN
rnt.output.success	Logs indicating successful completion of the process, such as BUILD SUCCESSFULL and others

Now you can customize React Native Tools output logs with editor.tokenColorCustomizations parameter in settings.json this way:

 "editor.tokenColorCustomizations": {
        "textMateRules": [
            {
                "settings": {
                    "foreground": "#c57ca0",
                    "fontStyle": "bold",
                },
                "scope": "rnt.output.string"
            }
        ]
    }
