Of course, if you want to show off new numbers, we'll be glad to tell you they're unsatisfactory
The following rant/plea is NOT directed at Jeb:
We've been regressing on car number/class readability for a while now.
As a T&S worker, I got pretty frustrated with some of the examples I tried to decode last season. Some were just cobbled togther and unreadable from the bus, but some others were carefully crafted, and still unreadable.
The recommendations for class/numbers are still posted on our website:

In addition to noting that red/black doesn't provide enough contrast, I can also tell you that yellow/white is worse. Adding a dark border around numbers that don't contrast with the body of the car really doesn't help much either.
Finally, the paper numbers are just a stop-gap measure for novices (first 3 events in my world) or if your numbers are already claimed. If you're running regularly, please get some real magnetics or cling-on numbers and letters. The blue tape frames around the paper numbers hurts readability. Having the paper number peel off during a run (and not fixing it before your next run) is also a problem.
Thank you.
