blue flash

Similar in most ways to the green flash, the wavelength-dependent refraction that gives a red rim on the low sun's bottom would be expected to give a blue rim on its top.

Often scattering diminishes the relative spectral radiance of the shortest wavelengths sufficiently that green is perceived, but not always.
