Yes take your VIN number to the dealer as the code is not posted anywhere on the vehicle. Let's see, an '05 Red should be Blaze Red Crystal Pearlcoat...I have an appointment tomorrow morning with a professional to repaint the edges of my doors. Something I should have seen when I bought it but maybe I was blinded by the Flash, LOL!
Your dealer can decode your color from the VIN...depending on the build date it could either be the Blaze Red Pearl or Inferno Red.
