Writing for FastCoDesign, Amber Case writes how the blue light that iPhones give off make us miserable by messing with our circadian rhythms. iPhones and Macs can counteract this with Night Shift, but is that enough? We should look to the military, which uses orange for dense information displays.
[Harvard researchers] found that blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours compared with 1.5 hours). And worse, it’s been linked in recent studies to an increased risk of obesity and some cancers.
Airplane cockpits, submarines, and other military-grade systems are specifically designed for information density, with primary, secondary and tertiary information sources. A key difference in all of these interfaces is color–by and large, many military displays are deep red or orange.
