Paint color might not be as big of an issue for people's orders as we thought.

In Rivian Stories' latest interview with John Rhodes, who attended the Rivian pre-order holders event, he told them that Rivian can run their vehicles down the paint line with 1.5 meters of separation (4.9 feet) and have them painted in different colors (ie the first truck is Rivian Blue then the next one right after can be Forest Green etc.). They don't have to paint large batches of colors at a time.
