Research at Exeter University into equine vision is leading to trials of new fence and hurdle color designs on horse racecourses to further improve safety in jump racing.

The colors deployed on hurdles and fences on British racecourses may be set to change following cutting-edge research led by the University of Exeter into the way that horses perceive color.
In 2017 the British Horseracing Authority (BHA) and Racing Foundation commissioned – and provided funding support for – research into equine vision.
The opportunity for this project 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
The research was undertaken by Dr Sarah Paul and Professor Martin Stevens of the University of Exeter with the aim of improving obstacle visibility for horses, therefore reducing the risk of falls and injuries for horses and jockeys.
Presently, the color used on hurdle frames and fence take-off boards and guard-rails is orange, based on human vision.
However, horses have reduced color vision compared to humans, and only differentiate objects in a palette of blues and yellows.
The new research shows that other colors should be more effective in offering visibility to horses.
As a result of the research, a recommendation has been approved by the sport’s Racecourse Committee that a phased trial should be carried out using fluorescent yellow for all hurdles and guard-rails, and fluorescent white for take-off boards at fences.
These colors have been determined to maximize visibility under a wide range of conditions for both humans and horses.
The research phase of the project included testing the visibility of orange markers and other potential colors at 11 racecourses, and – in collaboration with trainer Richard Phillips – testing the behavioural responses of horses to more prominent colors in a controlled environment.
Retired jockey Ian Popham and conditional jockey Danny Hiskett acted as riders of the horses throughout the trial.
It has now been agreed that the next phase of the project should see a more extensive trial take place at training grounds in order to build up a significant data set before rolling the trial out to a live racing environment.
The results of this research and the ongoing trials will be shared with other racing jurisdictions and equine organizations.
At the same time, the BHA and RSPCA are continuing to work together on a project to see if any further improvements can be made to the construction of hurdles, alongside the different use of color.
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.
“As with the ongoing phased introduction of our padded hurdles – which have proven to reduce faller and injury rates – we will ensure to take our time with this project, make sure there are no unintended consequences and that the evidence of the ongoing trials continue to support the case for change.
“If that proves to be the case then we will look forward to seeing the new designs of hurdles and fences on racecourses, and hopefully further reducing our already declining faller rate.”
The faller rate in British racing has reduced by 29% since 2004 as a result of ongoing investment in racecourse safety, and constant enhancements in racehorse care and training standards.
Professor Stevens, Chair in Sensory and Evolutionary Ecology for the University of Exeter, said: “Understanding how animals see the world, and using cutting-edge tools to investigate this, has a valuable role to play in guiding the safety and welfare of animals and humans in a variety of contexts.
“This project demonstrates how modern science can look to have widespread positive implications in human society and our interactions with animals.”
