We have deliberately chosen monochrome (single-color) displays because they are much more energy-efficient than multi-color displays! Thus, you benefit from up to 12 hours of battery life and can relax for a complete day trip and usually even beyond rely on your Tilsberk head-up display without having to recharge in between.
In addition, this decision also has a safety aspect: We did not want to additionally restrict the viewing area available to you by covering it with colored image overlays and graphics. Furthermore, the color we use for the overlays in the display does not occur in nature. So you benefit from an optimal visibility of the superimposed information, which cannot be covered by things of the same color etc. in the environment.
