One of the effective tools  WorkSafe traffic control uses is strategic uses of colours. You see, colours are widely used in a variety of industries. You can see them in interior design, architecture, biotechnology, physics, marketing, films and so much more. That’s because colours have a large impact on human psychology. 

Studies show that colours could change the alpha brain waves. That means when colour is perceived by the eyes, the signal is delivered to the brain. The brain then releases a hormone that affects the emotions, mental clarity and energy levels of the person who perceived this colour. No wonder choosing the rights colours for traffic control is so critical. They affect how a driver and any other person on the road can feel and react. These feelings and reactions can determine the likelihood of accidents on the road. 

That’s why WorkSafe traffic control mastered how to effectively use colours in managing road traffic. So you can use these colours in keeping pedestrians, workers and vehicles safe in your area.

If you’re ready to learn more about how to streamline the flow of traffic near your work zones, then keep reading. In a few minutes, you’ll discover how traffic management companies use different colours to influence the flow of traffic and maintain safety near your work zones. 

Let’s get it started. 


The Different Colors on The Road, And What They Mean

Traffic control companies streamline the flow of traffic through effective communication. Effective communication can be the key to accident-proofing your area. They can notify drivers and pedestrians of what to expect on the road. So that they can prepare themselves mentally and physically. 

To achieve high-level communication, WorkSafe traffic control uses colours effectively paired with signboards. Then, they are placed strategically on the road. 

Because the truth is, the colours used for the sign should say as much as the entire sign itself. When things are happening fast, the drivers should be able to tell what to do almost instinctively just by looking at the colours of the sign. 

These colours are messages themselves that should instruct the motorists, drivers and pedestrians how to behave, react or prepare for the road ahead. Here are some of the colours you should be aware of.

Red exudes the strongest emotions among all the colours. Because this colour has a long wavelength, it’s one of the most visible colours to drivers and pedestrians. That’s why this colour is used to warn people about a possible danger, for example, red traffic lights and fire engines.

Because it symbolizes impending danger, traffic control companies use it to instruct drivers and pedestrians to minimize hazardous behaviour.  Most signs that use the colour red mean “Do Not Enter”, “Yield” and “Stop”. These signs prevent drivers from entering areas with dangerous obstructions on the road, events, road constructions and prohibited streets. These signs prevent accidents from happening on the road.

Cool colours like green are considered peaceful and calming. Hence, it’s used to alert drivers with less threatening information. Unlike the red coloured signals, the colour green is used for signals that are not commanding immediate action. Examples of signs that use green are highway exits, emergency exits, first aid signs and other signs that state directions. This information is often relevant depending on the driver.

Like the colour green, blue is also a calm and peaceful colour used entirely to inform drivers. Rest stops, hotels, gas stations and restaurant signs usually use the colour blue to inform drivers of their locations.



Being an earthy colour, the colour brown suggests an area nearby dedicated to outdoor activities like picnics and campgrounds.

Because yellow is the most visible colour in the colour spectrum, it makes a signal stand out and easily grabs pedestrians and drivers’ attention. In fact, in the late 1920s where reflective aluminium wasn’t used on traffic signs, yellow was used on stop signs because of its visibility even at night time. Today,  yellow is used to call attention to instructions and important information. Often, it symbolizes a general warning or caution that there’s a permanent hazard ahead.

Orange, like the other warm colours, is used to warn people about a temporary hazard ahead. Usually, this colour is correlated with constructions, such as road constructions.


Black and White

The colours black and white are often correlated with clarity. Signs that use these colours are often advisory and warn against upcoming potential hazards with clarity. The drivers then adjust their speeds in order to adapt to this potential hazard. Samples of signs that use these colours are railroad crossing signs, movement regulations and speed limit signs.


Different colours have different impacts on a person’s feelings and reactions. That’s why effective traffic management solutions include proper use of these colours in imposing road communications and safety, especially when there’s a potential road obstruction ahead. Whether there’s road construction or an event that’s happening on the road, effective use of colours can maintain drivers and pedestrian’s safety.
