Hello from Tampa, Florida

Did the colors on Florida's US shields have any meaning? Or was it just random?

Probably random. Take for example, US 1 and US 27. Both are N-S routes, but they got different colors (US 1 was red - US 27 was green). Both even passed through the same city (Miami) and both even parallel another Interstate! (I-95 and I-75)

That's the reason they were different colors. If they were the same color, they might be confused from a distance.

I think they were only planned so the same colors wouldn't intersect. The exception was when US 192 was extended to the end of US 27 (both green).
