Calder, Nelson and Collingwood moved through the blue, white and red grades at different rates rather than making a single leap to the next flag rank. Calder initially advanced at a respectable pace, but Nelson and especially Collingwood gained seniority more rapidly after distinguished service. Following Trafalgar, Collingwood moved directly from Vice Admiral of the Blue to Vice Admiral of the Red while Calder rose only to White. Calder eventually reached Red, so a slowed career did not necessarily end an officer's prospects. The comparison makes the colour system a measure of reputation, sea-going value and suitability for particular commands as well as length of service.
