Tonight ISS pass was one of the brightest pass of ISS with magnitude of -4.0 that entered Earth shadow at 70° altitude and thats where I was waiting for it. in photo you can see the brilliant white ISS goes bluish and then deep red till reach total darkness of Earths shadow. these colors are the same colors that appears on Moon on Lunar Eclipses. blue color is the result of red color absorbtion by Ozone Layer of Earth and red color is remaining part of spectrum after Rayleigh scattering of light in lower earth atmosphere.

Why are stars visible at point of entry?

Stars are self luminous bodies and very farther than ISS. but ISS is illuminated by light of sun. inside the shadow of Earth no light will reach it to be reflected.
