Wouldn't that be red light? But night scenes illuminated in red light have the side effect of looking nightmarish..
- ijk 7mo agoThat's not necessarily a downside for traffic safety, though. Though I imagine someone must have studied the effects of various wavelengths on drivers...
- TeMPOraL 7mo agoAdvertisers definitely did - there's (some) money in billboards, but only as long as you don't kill your prospective customers.
- adrian_b 7mo agoRed light would be even better for affecting the dark adaptation, but it has other disadvantages, like much worse energetic efficiency and lower visual resolution. Yellow light a.k.a. amber light around the sodium emission line is a good compromise between energy efficiency, visual resolution and dark adaptation.
