OnePlus has announced that the “thunder purple” variant of the OnePlus 6T smartphone will be available for purchase in North America and Europe starting on November 15th. The special purple variant first debuted in China last week.

Much like the midnight and mirror black versions of the 6T, the thunder purple model is available with 8GB of RAM and 128GB of storage and will sell for $579. All of the other features, including compatibility with Verizon and the in-screen fingerprint scanner, are also available on the thunder purple model. The purple color way isn’t a solid color, but a gradient that fades from black to purple from the top to the bottom of the phone. It has a smooth, matte finish, like the midnight black model, and retains the “S-curve” that’s visible under the glass when it reflects light.
