The ability
to choose the backlight colour for the control panel, and sometimes also for the radio display. The specific range of shades available can vary, whether it be a few colours or the entire
RGB palette; see "Illumination colour" for details. Anyway, this feature does not play a functional role, however, it allows you to customize the appearance of the device so that it is in harmony with the appearance of the dashboard and matches the user's mood.
The colour of the backlight plays primarily an aesthetic role, allowing you to choose a radio for the design of the dashboard and user preferences. In addition, some colours have a practical meaning. So, the
red backlight is extremely popular nowadays also because it is almost perfect for the dark time of the day: this shade does not knock down "night vision" and has a stimulating effect on the nervous system. And
green, on the contrary, relieves excessive nervousness and promotes peace of mind. Other popular colours in modern times include
white,
blue,
orange,
yellow,
purple ; they do not have such pronounced effects, here the main selection criterion is “like or dislike”.
Also note that in many models several backlight colours are indicated at once. This means that the device has a backlight with adjustable colour selection. At the same time, there are models with a choice of a full range of RGB colours.
