> I can't focus properly on bright blue things. No one can, for a bunch of reasons. The eye is mostly corrected for red-green wavelengths; the eye is a lot less sensitive to blue light; there are far fewer receptors for blue light, which reduces spatial resolution. Monochromatic blue displays are an extreme UI antipattern and should not be used for anything. If combined with high luminosity, they become essentially unreadable unless close up. E.g. ultra-blue seven segment LED displays. VFDs can suffer from this, but this is also the reason why many of them use green-blue phosphors, and not blue phosphor (which would be possible). |
