Walking through the auto show today, I noticed the only interactive piece of the entire experience (other than getting in and out of cars) were the areas where customers pick car colors. Car companies had an amazing array of ways to entice customers to engage in choosing their car color. Apologies for the mediocre photo quality of my cell phone camera.
Above is a traditional color sheet - seen in 2009.
