 Most notably, the colour used by the Cambridge University Boat Club is different from that used by Cambridge University R.U.F.C..The current Boat Club colour was created when Alf Twinn, Cambridge University boatman 1934–1984, added more yellow to this shade, allegedly in order to distinguish it from the rugby club's colour.The Cambridge University official colour style guide defines Cambridge Blue as Pantone 557; with RGB values of R 163, G 193, B 173.
