+# Basemap Flavors
+
+These examples use the preferred [MapLibre GL JS](/basemaps/maplibre) library.
+
+The `Flavor` TypeScript interface is the preferred way to customize the basemap style. See the shape of the interface at the [@protomaps/basemaps TypeScript docs](https://maps.protomaps.com/typedoc/interfaces/Flavor.html).
+
+A `Flavor` is a plain object of color definitions and optional properties such as font names, landcover shades and POI properties. You can define a `Flavor` yourself for a custom style, similar to a text editor color scheme, or use one of the default named flavors as a base.
+
+## Default Flavors
+
+These flavors are included as part of the `@protomaps/basemaps` package.
+
+### light
+
+A general-purpose basemap with icons.
+
+<MaplibreMap flavor="light" :zoom=13 :lat="51.509" :lng="-0.14"/>
+
+### dark
+
+A general-purpose basemap with icons.
+
+<MaplibreMap flavor="dark" :zoom=13 :lat="51.509" :lng="-0.14"/>
+
+### white
+
+A flavor for data visualization.
+
+<MaplibreMap flavor="white" :zoom=13 :lat="51.509" :lng="-0.14"/>
+
+### grayscale
+
+A flavor for data visualization.
+
+<MaplibreMap flavor="grayscale" :zoom=13 :lat="51.509" :lng="-0.14"/>
+
+### black
+
+A flavor for data visualization.
+
+<MaplibreMap flavor="black" :zoom=13 :lat="51.509" :lng="-0.14"/>
+
+## Overriding Defaults
+
+Use [ES6 spread syntax](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax) to override any part of the Flavor object. For example, to color buildings red:
+
+```ts
+import { namedFlavor } from "@protomaps/basemaps"
+let flavor = {...namedFlavor("light"),buildings:"red")
+```

 ## Loading styles as JSON
 
-Because [MapLibre styles](https://maplibre.org/maplibre-style-spec/) are JSON documents, the simplest way to define a style in your application is with static JSON. You can use the `Get style JSON` feature of [maps.protomaps.com](https://maps.protomaps.com) to generate static JSON for a specific theme and style package version.
