EDIT: After posting this, I realized that the question was probably unnecessary according to common sense (G2), so I moved it out of the official Q&A to prevent clutter. I assume that the bolded phrase in R5b is referring only to functional uses of these materials, and that they are indeed legal to use as nonfunctional decorations.
I have left the question here so that no one is left wondering about where it went, and in case it turns out to be more important than I realize.
Here is the original question:
According to R5b:
On the other hand, R5d says:
Am I correct that it would be legal to use “VEX apparel, competition support materials, packaging or other non-robot products” as a non-functional decoration, provided that (1) these do not affect the robot performance in any significant way or affect the outcome of the match, and that (2) no other rules are violated?
Thank you so much for your time.
