2023 Infiniti Q50 with rainbow color option.

The 2023 Infiniti Q50 will add an iridescent paint option to bring some shine back to the aging sedan.

The iridescent paint, called Black Opal Metallic, is part of the Black Opal Edition package for the Q50 Red Sport 400 trim level. According to an Infiniti press release, the base black color shifts between blue, green, and purple depending on lighting and viewing angle.

Iridescent paint has been applied to production vehicles before, with the Nissan GT-R's midnight purple being a notable example. However, the complexity of the paint job makes it difficult to repair scratches and crash damage, and actually owning a car with this trippy paint job may be a hassle.

In addition to the paint color, the Black Opal Edition comes with satin black exterior badges and an unpainted carbon fiber rear spoiler. This package is only available on the most powerful Q50 variant, the Q50 Red Sport 400, with a 3.0-liter twin-turbo V-6 engine producing 400 hp and 350 lb-ft of torque, a seven-speed automatic transmission, rear-wheel rear-wheel drive or all-wheel drive.

The Black Opal Edition package is priced at $2,200 and the base price for the Q50 Red Sport 400 is $57,575 including destination. Infiniti also offers Luxe and Sensory trim levels that sit below the Red Sport 400. These are powered by a 300-horsepower twin-turbo V-6 engine and start at $43,725 including destination.

The Q50 was introduced in 2013 as a 2014 model, making it one of the older vehicles on the market, and aside from the new Iridescent paint option, it will remain essentially unchanged for 2023. While some rivals, like the Mercedes-Benz C-Class, have been redesigned twice while the Q50 was on sale, there is no clear successor to the Infiniti sedan.
