Traffic light signs have three colors: red, yellow, and green. Red means stop, yellow means slow down or prepare to stop, and green means go.
Traffic lights are illuminated. They emit light to signal drivers with colors like red, yellow, and green. The light source within a traffic light enables it to be visible during different times of the day and in various weather conditions.
No not at all.
Different Colors Of Light Travel At Different Speeds.

I believe that a range of light of different colors and different wavelengths is a spectrum.
In the riddle "What did red say to green?" the answer is typically "Stop!" This plays on the common traffic light colors where red means stop and green means go. It's a clever way to highlight the contrasting meanings of the colors in a playful context.
Different colors of light have different wavelengths. When white light passes through a prism or another medium, it gets separated into its component colors based on their wavelengths. Our eyes have receptors that are sensitive to these different wavelengths, allowing us to perceive the colors of light.
There's nothing really special here, it's simply the color of the light that enters our eyes is how we see the traffic light.

Traffic light colours have different shapes in order to inform the colour blind what colour the light is.
Traffic light colors indicate the rules for vehicles and pedestrians at intersections. A green light means go, allowing traffic to proceed. A yellow light warns that the signal is about to change to red, prompting drivers to slow down and prepare to stop. A red light signals that vehicles must stop and wait until the light turns green again.
Yes, light can appear in different colors depending on its wavelength. Different wavelengths of light correspond to different colors in the visible spectrum, such as red, blue, and green. Objects appear to have different colors based on how they absorb and reflect light of varying wavelengths.
