You may not know this, but many of the things you see every day have certain colors for very specific reasons. This is not just a whim or a matter of taste. BigPicture.com explains why toilet paper is white, hydrants are colorful, school buses are yellow, etc.
School buses
Everyone has seen yellow buses in American films that pick up children in the morning and take them to school. But why exactly yellow? It turns out the reason is pretty mundane. The decision that school transport should be of this color was made in the United States back in 1939, considering that it attracts attention and is easy for other drivers to notice, even in the dark.
Taxi
Taxis are colored the same for the same reason. Yellow cars stand out from others, and this color makes them easily recognizable.
Passenger airplanes
Most passenger aircraft are painted white to reflect sunlight. This little trick helps reduce sun damage and prevent aircraft from overheating. In addition, the white color reduces the cooling time required when the aircraft is at an airport.
Hydrants
In some countries, fire hydrants are colored differently to show how many gallons of water per minute they can produce. In addition, different hydrants are used to extinguish different types of fires, depending on their size. The most popular colors are red, orange, green and blue.

Tires
The rubber used to make tires is actually white, but carbon black is added to it to extend its life. It is he who is “to blame” for the tires becoming black. Carbon black increases the strength and durability of tires by dissipating heat and protecting them from UV radiation.
Crosswalk
Contrasting black and white colors make the zebras visible even from a distance. This gives drivers enough time to slow down and allow people to cross the street. In addition, these 2 contrasting colors also help pedestrians stand out from the background, which helps prevent accidents.
Football balls
When soccer balls were made of plastic, they were all white. However, Adidas decided to add black to them as well. Black and white balls were easier to see on the TV screen, because the picture on television at that time was also black and white.
Traffic light
The choice of colors for a traffic light fell exactly on red, yellow and green, due to several factors. Firstly, red has always been associated with danger, while green, on the contrary, was perceived calmly. Secondly, red is the color of a long solar wave, so it can be seen even from a great distance. Yellow was chosen because it has a shorter wavelength than red, but not as short as green.
Toilet paper
Most often, toilet paper is white, although it looks brown in its raw form. There are several reasons for manufacturers to bleach paper. The main one is the same as for toilets. White is associated with purity and looks more natural than brown. In addition, the bleaching process removes the polymer lignin, which makes the wood fibers dense. Removing the lignin prolongs the “life” of the roll, so it can be stored for a long time in the warehouse and sold on shelves. You also often see multi-colored toilet paper. The dyeing of rolls in different colors began in the middle of the twentieth century, so that people could combine them with the interior of the bathroom. But soon the popularity of such paper faded away, as many doctors insisted on the dangers of dyes to health.

Social media apps
Have you noticed that almost all social media icons are blue? Developers use it because it is closely related to intelligence and reason, and therefore the act of communication. In addition, blue resonates with a sense of reliability, trust and stability. For this reason, many posters during the race are also blue or light blue.
