How do I change the colors of selection elements in Illustrator from white to something else?

Question

Design

Version CC 2015.2.1
The essence of the problem: For

some reason, the chandelier colors the selection interface in white (it used to be blue, like a frame around the perimeter).
This is somehow imbecile, because it merges with the background. What to do?

Answer 1

In general, the color of the selection border is the color of the layer. It's just that there is no white.
More information would be.
