Radio is the first wireless mobile communication equipment used by human beings, as early as the 1930s began to be used. After nearly a century of development, the application of the walkie-talkie has become very common, from specialized fields to ordinary consumption, and from military to civilian use. So, the question arises, no matter how the walkie-talkie looks different, but in terms of color, why are most of the walkie-talkies still "black"?

Maybe for the following reasons:

We usually say "black technology", technology is born with bright black, which is in line with social psychology.

Black represents the unknown, and the exploration is never-ending! The color used for many technological products, such as televisions, cameras, stereos, and instruments, is mostly black.

Most of the people who use the walkie-talkies are men, and the black color brings out the spirit and competence of the characters. Of course, when women wear walkie-talkies, it is also a beautiful landscape.

With the development and progress of society，everything is changing.In order to distinguish the style and show the personality,colorful walkie-talkies also appeared.
