Best answer: Right now, the Thunder Purple OnePlus 6T is the best color option to get if you're in the market for a device that stands out. It has a gradient pattern underneath the glass back that alternates between black and purple, and is one of the most evocative finishes we've seen on a phone this year.
OnePlus: OnePlus 6T ($549 - $629)
Thunder Purple is the perfect color for the OnePlus 6T
OnePlus outdid itself with the Thunder Purple color variant. The gradient pattern at the back is subtle, switching between black and purple, and the company's signature design flourishes add to the effect.
The "S" curve is visible across the back, and the sides of the phone also have a similar gradient effect, with the alert slider featuring a black hue that fades into purple as it reaches the power button.
Go with Midnight Black if you prefer a less flamboyant color
You also have the option of choosing between a glossy or matte finish in black. The Mirror Black is the default color option, and it comes with a glossy finish that's prone to smudges. The Midnight Black, meanwhile, has a matte finish that makes it easier to hold, and it doesn't smudge as much.
The Mirror Black option is available with the 6GB/128GB and 8GB/128GB storage options, and the Midnight Black variant is limited to the 8GB/128GB and 8GB/256GB models. So if you want to get the Midnight Black finish, you'll be shelling out a minimum of $579 for the 8GB/128GB model.
OnePlus is also known for launching Disney-themed collaborations for customers in India, like the OnePlus 6 Marvel Avengers Edition. We don't know when these variants will be made available, but it's possible we'll hear more updates on this front before the end of the year.
A fantastic phone with a color option to match
If you're eyeing the OnePlus 6T, the Thunder Purple option has plenty to offer. The gradient effect combined with the matte finish make it one of the most attractive designs OnePlus has launched to date, and the fact that it's a limited-edition hue makes it exclusive.
