+### `require('supports-color').supportsColor(stream, options?)`
 
+Additionally, `supports-color` exposes the `.supportsColor()` function that takes an arbitrary write stream (e.g. `process.stdout`) and an optional options object to (re-)evaluate color support for an arbitrary stream.
+
+For example, `require('supports-color').stdout` is the equivalent of `require('supports-color').supportsColor(process.stdout)`.
+
+The options object supports a single boolean property `sniffFlags`. By default it is `true`, which instructs `supportsColor()` to sniff `process.argv` for the multitude of `--color` flags (see _Info_ below). If `false`, then `process.argv` is not considered when determining color support.
