Seventy Percent Blue is an online information resource, created by Richard Devanney in 2017. The original idea was for a simple but comprehensive online information resource for the diving community to go to for all things diving. The four main themes being scuba diving, technical diving, freediving and underwater photography and filmmaking.

The inspiration was that all other existing websites were not very good and were mainly just about self-promotion, with nothing of any real substance behind them. Articles on diving are usually really dumbed down for the sake of getting someone’s attention long enough to bombard them with adverts.

The people most involved with Seventypercentblue, in order of alcohol dependence and worst to best haircut, are:
