[wtqflfwv] Bright F star

The eye is most sensitive to photons emitted by stars of the F spectral class.  Unsurprisingly, they appear white.  F is one category higher than the yellow G class of our Sun.

Not green, which lies between yellow and blue in the rainbow and is the pure frequency to which our eyes are most sensitive.  Stars, approximately black body radiators, do not emit pure frequencies but a broad spectrum.
