Dark mode for in-car HMI is a safety requirement
In-car interface dark mode is not a preference toggle — it is the primary mode during nighttime driving, and getting the contrast wrong is a safety hazard. Glance time for in-car displays should not exceed 1.5 seconds, which means every element must be instantly distinguishable. Use a surface base no darker than 12% lightness to maintain panel separation, and ensure critical controls (speed, navigation, warnings) use colors with at least 7:1 contrast against the background. Nocturne Tech is built around these constraints: its surface steps are calibrated for the extreme dynamic range between bright daylight and nighttime driving conditions.
