Come on Sky news, really you can do better than this nonsense. In reality horses are challenged by certain bright colours, add the placement of these colours on the ground into the equation and obviously they will react. I don’t think this was taken into consideration when the pedestrian crossing was painted. Black, white, blue and yellow are known to have a negative effect on horses. The placement of the colour is also important as horses are very sensitive animals. The horse riders may not have been consulted over this colour change either or they would have suggested that it was not good for horses.
I know nothing about horses myself but looking at the video the first thing that came to my mind was the colour combination and perhaps depth perception. So a quick google search confirmed the colour combination.
