The blue is the perfect blue. It's bright but not to bright. I spent a while searching for fuel lines that fit my bike, as one is 3/8 from the fuel filter into the fuel pump, and 5/16 out of the fuel pump. Helix gave me super fast shipping and the fuel lines are flexible but do not tear easily. It is flexible, however, I tried to curve from the tank to the fuel filter and it kinked, due to the sharp roundness I needed. But other than that, SUPER AMAZING and Helix had the fuel lines I needed, as I struggled to look for the 2 sizes and in blue!!!
