Orange and Blue?
Several have asked.
It all started with the frame. That came first. It was orange.
I always admired the Gulf Oil GT40's that roared to victory in the sixties beating the Ferraris that held court at the time.
John Wyer was team manager and the color scheme stuck through the Audi A8's that were victorious at Le Mans in 2001.
Powder blue best descibes the Gulf blue (usually the dominant color) but the orange is close enough.

After struggling with the rear deraillier that jumped teeth on the smallest cog I broke down and took it to a bike dealer. Turns out the cassette lock ring was too large and was pushing the chain off. $25 for a new lock ring and $10 labor and I have nirvana. Again.
