Mandatory signs consist of an inscription in what color on a background of what color?

Explanation:
Mandatory signs convey actions you must follow. They’re designed to be immediately recognizable, using a high-contrast color scheme to signal obligation. In this material, that scheme is white inscription on a red background, which makes the directive stand out and clearly indicate a required action. The red background emphasizes the seriousness of the instruction, differentiating these signs from other categories like warnings or prohibitions. So the white-on-red combination is the visual cue for a mandatory instruction in this context.
