License plate debate

The plates for my new car came today.  Timing was good  because one of the dogs had a wild moment and pulled the temporary license off the back window.   I like to  name my cars.  This one could be called "Ruby".  But  can I call a dark blue  car ruby?

That is not the real debate.  I have been thinking about getting a personalized plate again.  I  used to have BACK4T until I moved back from  Wisconsin. Then I chose not to spend the extra money on personalized plates because I was focusing on my start up business.

My father's plates are BACK40 "Field" and my mother used to sign cards (to the grandparents) from the 4 T's.  All four of us kids have names that begin with the letter  T. I  might see if my old  plate is still  available "BACK4T" ... maybe.

Ruby (blue)?
