Depends on your use... for brightness, without a doubt green. 2 reasons to get technical, first the chemical make up allows that color to glow brightest, and second is that the human eye sees this color better than any other light wavelength. If you're looking for "flares" though and need red, your best bet would be a strobe light. The red snap lights are good for low-light needs (hence using red lens flashlights in the military to read maps as the human eye doesn't pick this light up at low levels), but nowhere near what you would need for safety. Blues and whites are in the middle but don't nearly as long -better off with a LED flashlight. Go green...

Cyalume9-00721 Snap Light Stick, 6", Red (Pack of 20)

Q: Can they be stored in freezing temps in a car? Gets Brutal in NY in the winter

they can be stored in the car and they will not freeze

Q: Is the shape like an octagon to avoid rolling on a flat surface?

Seems to not roll due to flat sealed end not to say it would not roll on a steep incline hope this helps

Q: Are these Coast Guard approved instead of light them up flares?

I can't give you any kind of legal advice ("...approved by Coast Guard..."), but I'd suggest to you that the soft and gentle glow of a Cyalume Stick would be quite close to useless if you were stranded out on the water and were waiting for the Coast Guard - anyone - to find you.
