 ## API
 
+### `open` and `close`
+
 Each style has an `open` and `close` property.
 
+### `modifierNames`, `foregroundColorNames`, `backgroundColorNames`, and `colorNames`
+
+All supported style strings are exposed as an array of strings for convenience. `colorNames` is the combination of `foregroundColorNames` and `backgroundColorNames`.
+
+This can be useful if you need to validate input:
+
+```js
+import {modifierNames, foregroundColorNames} from 'ansi-styles';
+
+console.log(modifierNames.includes('bold'));
+//=> true
+
+console.log(foregroundColorNames.includes('pink'));
+//=> false
+```
+
