Vermillion or Vermillion Red?
 

I thought that there was only one Vermillion Red color (Ford paint code E4). Today, I saw a 2010 truck with the paint code F1 called Vermillion. I've looked on different websites that say these two colors are the same... other sites say they're not the same. Does anyone know for sure if E4 and F1 are the same color? Thanks...
