Narrow Colored Streets

[LHowell1914]

I work with maps for a Real Estate Company, and need maps with narrow colored streets. I created one with the styling wizard, but don't know how to save it in a way I can use. Here is the JSON for it...can it be incorporated somewhere so that I can choose it as an option to use?

},
