Greetings! We wanted to know if these plates would be legal for competition. Thanks in advance!
Yes they are
Maybe not - the issue is you are using the opposing alliance color, RED, for your letters. So if in the opinion of the referee it is confusing to them, they you may have a problem.
I would stick with White or Black for number/lettering.
The inspector just has to make sure that everyone will be able to understand it. There was an official QnA answer about that recently, and that’s what they said.
