Have you ever wondered why the upholstery of seats in an airplane, mostly of a blue hue?

The airline tries to give shades of gray, blue or beige colors. Why, these colors ??
Yes, the fact is that the passenger seat in the airplane contributes to the tranquility, pacification and practicality of a passenger's rest.

And I want to say that the main reason for choosing blue for armchairs is the desire to provide an interior that will maximize comfort for passengers and create a pleasant environment for the flight and thus the brand of the airline make it more recognizable.
