Some interesting reading about our perception of colours Red is safest â€“ and most dangerous â€“ says research Research undertaken last month reveals confusion among riders about which bike colours are the safest. Red was voted as both the safest and most dangerous colour. There have only been two scientific investigations of the relationship between bike colour and safety (Lardelli-Claret 2002 and Furness et al 2003). Whilst neither was able to propose the selection of one particular colour as the unambiguous best choice for safety, the results of these studies did point towards lighter colours such as white and yellow being safer than dark colours such as black. A separate study of fire fighting equipment (Schuman 1991) stated that red, which is perceived as black at night, is one of the least visible of bike colours. The report also pointed out that people have particularly poor peripheral detection of red shades. â€œHowever, darker colours such as black, red and dark blue are probably less visible than white or yellow bikes this will depend to some extent on environmental conditions Research indicates that nearly a quarter of roadusers think that red is the safest colour â€“ probably because red is often perceived as a warning colour and is used by the fire services. However, over a third think it is the most dangerous colour Full details of the results are as follows: Safest colour/ Most dangerous colour; Red 23%/ Red 35% White 21%/ Black 29% Silver 17%/ White 10% Blue 15%/ Grey 9% Black 13%/ Silver 7% Grey 4%/ Blue 2% Other 7% Other 8% We also need to consider whether red is the most appropriate colour for emergency vehicles, such as fire engines. The research undertaken so far would seem to indicate that lime yellow would be a more visible colour.
