There is a discussion on Hacker News, but feel free to comment here as well.
This would be illegal in my state. Amber and red visible from the rear and white, yellow, and amber visible from the front. Regardless, blue isn't a good color because it's reserved for emergency vehicles. Should have gone with green.
My state, too (Indiana, for reference)
I'd go with Purple/Violet. Not a color light you really see anywhere on roadways so it would stick out easier.
Purple is for rain.
To confuse with traffic lights, brilliant! But seriously, the amount of people that hit the gas when they see green in their periphery is high.
Which state is it?
Wisconsin, but I think a lot of states have a similar law. But yeah green maybe isn't the best choice either.
Red-green colourblindness is the most common type, perhaps it's best to use a more distinct colour.
