In Frank Sinatra's song "Something Stupid", He says:
The time is right,
your perfume fills my head,
the stars get red,
and oh, the night's so blue.
And then I go and spoil it all,
by saying something stupid like I "love you".
I want to understand what does he mean by "the stars get red" and its relation to the night's so blue. As in my understanding that blue refers to sadness most of the time.
