Rivian R1S in a striking purple hue was recently spotted with manufacturer plates, suggesting it may not just be a custom paint job but possibly a prototype or test vehicle. The same vehicle has appeared in multiple public sightings, with the identical plates, hinting there may currently be only one such purple unit in circulation.

Rivian has not confirmed whether purple will become an official color option. Their only public comment so far was non-committal: “We have nothing to add. As you know, we don’t comment on any speculation.” Meanwhile, fans on social media and EV forums have been playing with possible names for this mysterious purple.

If Rivian did introduce purple as a selectable exterior color, it would expand beyond their current boldest option, “Rivian Blue,” and give customers a more vibrant choice.
