Bumper Number Question

[burde1jb]

Okay. I know bumpers are everyone's favorite topic right now at the end of build season.

Per the rule book:
R28
Team numbers must be displayed on the BUMPERS and meet the following criteria:

consist of numerals at least 4 in. high, at least ½ in. in stroke width, and be either white in color or outlined in white,
may not wrap around a corner of the FRAME PERIMETER (for the purposes of R28 a round or circular FRAME PERIMETER has no corners), and
be positioned around the ROBOT such that an observer walking around the perimeter of the ROBOT can unambiguously tell the Team’s number from any point of view.

My question is if numbers which are white, but outlined in another color would pass inspection. In particular, these: https://www.numbers4sports.com/produ...rple-4-inch-*7

Thanks for your thoughts ahead of time!
