Ok, well after reading through 12 pages of posts I have an idea. What if the 5 relates to the number of zones. 2x2 alliance, robots in starting zones 1-4. In the center is a raised platform, zone 5. Notice how the edges on 2 sides are straight not round, that could indicate a ramp to the platform. Also, while the blue is the same background from kickoff, I think it means we will be using a blue light for some reason or another.
