Colors

[dmaze]

I think this question is mostly for ilai. But it's a detail sort of thing.

Stand at the southeastern corner of Beacon St. and Somerville Ave., preferably after dark. Look at the signals on the commute rail; look at the traffic lights. Are they actually different colors? (And if so, why?)

I had just assumed they would want them a little different for when they need to know which is theirs. But if it's because they're bought from different people, that could be sorta like Arial vs Helvetica.
