Apparently Pepsi didn’t get the piss yellow memo, and here we have another example of why it’s a terrible color for a race car. It’s not just IndyCar, NASCAR and the NHRA also fell victim to the Pepsi Challenger design. Did Pepsi not realize that they have a great color scheme? Red, white, and blue is a color scheme that rarely misses, but for some unknown reason, Pepsi thought that piss yellow was the way to go…which it wasn’t. I’m giving this scheme an F.
