My question is if numbers which are white, but outlined in another color would pass inspection.

The numbers are white 4" high with a 1/2" stroke width. Seems to meet the criteria. However, some inspector could make the claim that the number is 4" high, but the white is only 3.75" high because of the 1/8" purple perimeter.

However, given the following rule (emphasis mine):

R27
Each ROBOT must be able to display red or blue BUMPERS to match their ALLIANCE color, as assigned in the MATCH schedule distributed at the event (reference Section 5.1.1: MATCH Schedules). Markings visible when installed on the ROBOT, other than those explicitly required per R28, are prohibited.

I would have to view the outlined numbers with some suspicion. However, if other teams have used the successfully in the past, then it's probably all good. Given some of the bumper numbers I've seen in the past few years, I cannot imagine that this would be a problem.
