Cambridge Blue is the colour commonly used by sports teams from Cambridge University. There is considerable dispute regarding the exact shade of the colour that should be used. Most notably, the colour used by the Cambridge University Boat Club is different from that used by the rugby union club. The Boat Club colour was created when Alf Twinn added more yellow to this shade.
