The colour of markers on hurdles and fences at racecourses could change because of the way horses see colour. Research by the University of Exeter found that racehorses may jump better over white and yellow obstacles, instead of the orange/brown which is currently used on hurdle frames, fence take-off boards and guard-rails.
The study on equine vision, commissioned by the British Horseracing Authority and Racing Foundation in 2017, involved noting the behavioural responses of horses to more prominent colours in a controlled environment. It was carried out with trainer Richard Phillips and 11 racecourses, where the visibility of orange markers and other potential colours were tested.
As a result, a phased trial at training grounds will begin using fluorescent yellow for all hurdles and guard-rails and fluorescent white for take-off boards at fences. The colours have been determined to maximise visibility under a wide range of conditions for both humans and horses.
The opportunity for the study was identified by the partnership between the BHA and RSPCA, who work together on an ongoing basis to develop new ways to make hurdle and fence design safer. David Sykes, Director of Equine Health and Welfare for the BHA, said: “This fine and important project is an example of how British racing uses advanced scientific and veterinary research to constantly improve racehorse welfare, not only for thoroughbreds in Britain but across other nations and equine disciplines. Results of the colour research undertaken by Dr Sarah Paul and Professor Martin Stevens will be shared with other racing jurisdictions and equine organisations.
