The blue bike is DuPont Hot Hues - "Blue Mood."
The DuPont paints are excellent products, but be prepared to spend some money. The silver 78F is painted with Duplicolor Paint Shop Black and "Brilliant Silver." That paint is not nearly as good as the DuPont product, but it's about 1/3 the price.
I will probably sell the silver bike next spring, since it's completely stock except for the paint, it's a very nice ride, but I prefer the lower bars, koni shocks, and kerker sound over that of stock 78F configuraion.
