Albireo, in the constellation Cygnus, is a visual binary system whose two components can easily be seen with even a small amateur telescope. Viewers describe the brighter star as “golden” and the fainter one as “sapphire blue.” (a) What does this description tell you about the relative temperatures of the two stars? (b) What does this description tell you about their respective sizes?
According to Wein's displacement law lambdameantemperature=constant

Thus the relative temperature of golden is lower compared to blue.
