Wut? Blue? Are you sure about that? Afaik the peak is around 555nm, yellow green. Why do you think we have "high visibility yellow" vests and not "high visibility blue?"

IIRC 555nm (or whereabouts) stimulates the L and M cones simultaneously.

Light vs dark adapted. In bright light, the best wavelength is longer.
