A blue is an award of sporting colours earned by athletes at some universities and schools for competition at the highest level. The awarding of blues began at Oxford and Cambridge universities in England. They are now awarded at a number of other British universities and at some universities in Australia and New Zealand.

Sporting colours or just colours are awarded to members of a university or school who have excelled in a sport. Many schools do not limit their use to sport but may also give colours for academic excellence or non-sporting extra-curricular activities, Colours are traditionally indicated by the wearing of a special tie or blazer.
Pupils who are awarded Colours at Christ's Hospital school, receive a tie, and in the case of sporting colours awarded for cricket, they also receive a cricket cap with the school crest and cricket 'XI' embroidered at the front.
