I like my vehicles to have 'color'. So I tend to stay away from black, white, grey. I like the bright and/or out there colors.
I liked the Rivian Blue too. And I thought for sure that would be their 'launch' color when I watched a video with RJ in it and he said they liked the blue so much they painted their robots that color. So, I was disappointed when it was not, but not going to pay that much extra for it.
The Launch Green also varies in the pictures. This is the color I went with. Hoping it is more green then brown (couple pictures make it look brownish).
Hopefully at some point we will get to see the colors in person.
