In New Mexico they have at least three different colors and designs of vehicle license plates.  I don’t have the foggiest idea why there is this difference.  My favorite one is teal blue.

They have a black plate with yellow letters and a big chile pepper on the left.  The pepper is multi colored and almost looks iridescent.  They have the teal plate with yellow letters and a sun motif in the middle.  And they have a yellow plate with red letters and the same sun motif in the middle.

In Albuquerque the overpasses are painted a rosy adobe color with a teal blue stripe on the outside edge.
