The photo was taken on a gloomy winter day. The fence secures a huge photovoltaic plant. You can see the back of the panels.

The yellow warning sign caught my eye as a colorful spot in this monotonous and technically sober environment.

In the image processing, the colors were taken back a bit without emphasizing the yellow sign through processing. So the image captures my personal perception of the scene well.

The shot was taken during a walk without any lengthy preparation or planning.
