Scientific studies show that white is more visible at night and lime yellow during the day. If it would save on production cost allowing EM to stay closer to their $6800 target price they should offer only two factory color options: white and lime yellow and possibly a third two tone color option: white and lime yellow placing the emphasis on economical safety. A fourth option might be primer grey allowing for custom paint colors of choice upon delivery. Aren't you glad I'm not on EM's Paint Color Selection Team!
