Our survey resulted in a reasonable luminance of 500 cd/m 2 for blue (emphasized by blinking) and a RGB luminance ratio of 35:50:15. Additionally, the subjects had to adjust two neighboring colors to the same brightness or judge (brighter, same, and darker) for different colors.

The luminance of blue for вЂњannoyingвЂќ (= safe recognition) reached 900 cd/m 2 (sunlight+ blinding).

We tested 18 subjects (pandemic restrictions). The surrounding simulates night to sunlight conditions with additional 100,000 cd/m 2 blinding sun. EN12966) is 35:50:15.We designed our car mock-up for a white luminance of 13,000 cd/mВІ using a RGB LED stripe reaching 1,500 cd/m 2 for blue. Therefore we started an evaluation with different aspects as basis: The luminance of blue is low due to V(О») curve but its color perception is high by Color Matching Functions, the lightness L* (perceived brightness) is related to luminance L by L* ~ L 0.44 and the RGB luminance ratio of traffic signs (acc. A new proposal from an OEM requires the same luminance just for blue. wayfinding support, directional highlighting and turn signals.TodayвЂ™s white luminance of light guides is about 1,250 cd/m 2 for daylight with a RGB luminance ratio of typically 28:65:7.

Usage is safe visualization of autonomous mode and warnings beside e.g. Colored light for visual communication in cars at daylight conditions has recently started: A light guide with RGB LEDs is placed at the bottom of the windshield.
